20-61: WiremaxConnectionsQueuedtosetMaxWaitQueueSize; document or remove unused buffer/auth configs.The Vert.x
setMaxWaitQueueSizeis indeed the correct mapping for Jetty'smaxConnectionsQueuedsetting. The code currently accepts this parameter but leaves it unused, which will confuse operators who set it expecting an effect.The following configuration properties remain wired in the method signature but are not mapped in the Vert.x options:
maxConnectionsQueued— should useoptions.setMaxWaitQueueSize(maxConnectionsQueued)requestBufferSize,responseBufferSize— Vert.x handles buffers dynamically; either remove from signature or document as deprecateddisableWWWAuthenticationValidation— Vert.x WebClient doesn't auto-handle 401; either remove or document the behavioral difference

66-77: RequestWrapper diagnostics (query params, toString) are fine; note params remain URL-encoded.The parsing of the initial URI query string into
queryParamsMapand its inclusion intoMap()/toString()is useful for debugging and does not affect the underlying HTTP request (sincerequestAbsalready includes the query). Just be aware that keys/values are left URL‑encoded, which slightly changes any logging compared to a decoded representation.No change requested here.
Also applies to: 78-94, 233-235, 271-275
39-49: Vert.x WebClient wiring verified and looks good.The
IHttpClient.Methodenum contains only standard HTTP methods (HEAD, GET, POST, PUT, DELETE, PATCH)—all natively supported by Vert.x'sio.vertx.core.http.HttpMethodenum. TheHttpMethod.valueOf(method.name())mapping is safe and will not throwIllegalArgumentException.
311-317: I need to verify a few more things to understand if this is truly a breaking change from the previous Jetty behavior.Now let me search the codebase for any references to old implementation patterns or migration notes:
Review comment is technically valid but contextually acceptable; verify intentionality.
Vert.x MultiMap supports multiple header values (multi-valued headers like Set-Cookie are common in HTTP), but the
convertHeaderToMapmethod converts it toMap<String, String>, retaining only the last value per key. This is a valid concern.However, verification reveals:
Vert.x MultiMap.get() returns the first value when multiple values exist for a header, not the last—the review's assumption about "last value" warrants clarification.
The
IResponseinterface already specifiesMap<String, String>as the return type, suggesting this single-valued design was intentional.Current usage (HttpCallsTask.java line 147) treats headers as single-valued:
response.getHttpHeader().get(CONTENT_TYPE).This is not a breaking change IF the prior Jetty implementation also returned single-valued headers. Without git history confirming otherwise, the interface contract suggests this was the existing behavior. If multi-valued headers (e.g., Set-Cookie) are required in the future, refactoring to
Map<String, List<String>>would be appropriate.Confirm whether the prior Jetty implementation supported multi-valued header access, and whether this application ever relied on it.
96-101: Concern aboutrealmandpreemptiveparameters being ignored is valid; however, the reference to lines 121-131 appears incorrect.The web search confirms that Vert.x HttpRequest.basicAuthentication only takes id/password and does not support realm or preemptive parameters. The implementation correctly ignores these parameters because the underlying Vert.x API does not accept them.
However, the reference to "Also applies to: 121-131" is misleading—those lines contain
setBodyEntity, which is unrelated to authentication. Additionally, a search of the entire repository found no call sites forsetBasicAuthentication, so there is no evidence within the codebase of callers that would be affected by the parameter change.If this is part of a public API consumed by external code, please verify whether any callers rely on
realmorpreemptivesemantics that are now lost. If this method is unused, clarify the intent. Also, clarify the reference to lines 121-131 or remove it.

🧩 Analysis chain
Blocking send() + async error handling: avoid hanging callers and event-loop blocking.
A few intertwined concerns here:
-
Sync
send()blocks on a future.
future.get()will block the calling thread until the Vert.x request completes. That preserves the old “blocking send” API, but ifsend()is ever called from a Vert.x event-loop thread, it will block that loop. Consider documenting thatsend()must be called from a worker / blocking thread, not an event loop. -
Async
send(ICompleteListener)swallows failures.
WhendoSendcompletes with failure (network error, timeout, or maxLength violation), theICompleteListeneris never invoked; you only log the error in theelsebranch. That means callers using the async API have no signal that the request finished with an error and can hang waiting for completion.You probably want a strategy such as:
- invoking
onCompletewith a syntheticIResponsedescribing the failure, or - extending the callback contract to surface failures explicitly.
- invoking
-
Interrupted status dropped in sync path.
Insend(), you catchInterruptedExceptionand wrap it inHttpRequestExceptionwithout re‑setting the thread interrupt flag. A small improvement would be:} catch (InterruptedException | ExecutionException e) { if (e instanceof InterruptedException) { Thread.currentThread().interrupt(); } throw new HttpRequestException(e.getLocalizedMessage(), e); }
Given this touches public behavior, I’d recommend at least deciding and documenting what guarantees send(ICompleteListener) should provide on error, and ensuring no production paths call send() from an event-loop thread.

Fix async error handling and interrupt flag restoration in HttpClientWrapper.
Two critical issues confirmed:
-
Async
send(ICompleteListener)never invokes callback on failure (lines 254-271): WhendoSendfails, the code only logs the error and never callscompleteListener.onComplete(), causing async callers to hang indefinitely. The failure branch must invoke the callback with a synthetic response or extend the contract to signal errors explicitly. -
InterruptedExceptionnot restoring thread interrupt flag (lines 154-170): The syncsend()catchesInterruptedExceptionwithout callingThread.currentThread().interrupt(), which loses the interrupt signal and can break cancellation semantics in calling code.
The concern about blocking on event-loop threads does not apply to this codebase—send() is called from runtime.submitCallable(), which uses ExecutorService.submit() (worker threads), not Vert.x event-loop threads. However, documenting the blocking nature of send() would prevent future misuse.

The Vertx instance is injected but Quarkus provides Vert.x through the quarkus-vertx extension. You need to add the Quarkus Vert.x dependency to pom.xml for this injection to work:
<dependency>
<groupId>io.quarkus</groupId>
<artifactId>quarkus-vertx</artifactId>
</dependency>Without this dependency, the Vertx injection will fail at runtime.

The realm and preemptive parameters are ignored. The Vert.x basicAuthentication() method only takes username and password and always sends credentials preemptively. This is a behavioral change from the Jetty implementation that could affect authentication with servers that require non-preemptive authentication or specific realms.
Consider documenting this limitation or, if realm-based authentication is needed, you may need to manually construct the Authorization header.

The maxConnectionsQueued configuration parameter is read but never used. The comment on line 34 notes that there's no direct equivalent in Vert.x WebClientOptions, but the parameter should either be removed from the method signature or a comment should be added explaining why it's not applicable.

Using CompletableFuture.get() in the synchronous send() method will block the calling thread, which could be problematic in a Vert.x or reactive context where blocking operations should be avoided on event loop threads.
Since this is wrapped in an ApplicationScoped bean and used in a Quarkus application, consider documenting that this method should only be called from worker threads, not from Vert.x event loop threads. Alternatively, consider using Uni.await().indefinitely() from Quarkus with proper context propagation, or ensure callers use this on appropriate thread pools.

The send() method uses CompletableFuture.get() which will block indefinitely if the request never completes, potentially causing thread starvation. While the request itself has a timeout set via setTimeout(), if that timeout isn't set, this could hang forever.
Consider adding a fallback timeout to the get() call:
return future.get(defaultTimeout, TimeUnit.SECONDS);or ensuring that a timeout is always set on the request.

| } |
There was a problem hiding this comment.
The timeout conversion from milliseconds to seconds using integer division can result in a timeout of 0 seconds (no timeout) for values less than 1000ms. For example, if idleTimeout is 500ms, idleTimeoutSeconds will be 0, which in Vert.x means "no timeout" rather than 500ms.
Consider using TimeUnit conversions or rounding up:
int idleTimeoutSeconds = (int) Math.ceil(idleTimeout / 1000.0);to ensure timeouts under 1 second are still applied as 1 second rather than being disabled.
| int idleTimeoutSeconds = idleTimeout / 1000; | |

| return this; |
There was a problem hiding this comment.
The setMaxResponseSize method no longer enforces the maximum response size during download. While the check is performed after the entire response is buffered (lines 192-201), this defeats the purpose of the limit, which was to prevent memory exhaustion from large responses.
Vert.x will buffer the entire response in memory before the size check occurs, potentially causing OutOfMemoryError for very large responses. Consider using sendStream() with a custom handler that counts bytes and fails early if the limit is exceeded, similar to the original Jetty implementation with BufferingResponseListener.

There was a problem hiding this comment.
The timeout is converted from the provided TimeUnit to milliseconds, but request.timeout() expects the timeout in milliseconds. If the provided timeout value is very large and the TimeUnit is something like DAYS or HOURS, the conversion timeUnit.toMillis(timeout) could overflow, resulting in incorrect timeout values or even negative values.
Consider adding validation:
long timeoutMillis = timeUnit.toMillis(timeout);
if (timeoutMillis > Integer.MAX_VALUE || timeoutMillis < 0) {
throw new IllegalArgumentException("Timeout value out of acceptable range");
}
request.timeout(timeoutMillis);| request.timeout(timeUnit.toMillis(timeout)); | |

| throw new IllegalArgumentException("Timeout value out of acceptable range: " + timeout + " " + timeUnit); | |
| } | |

The query parameter parsing logic can produce incorrect results when a parameter value contains & or = characters. The code splits on & and = without URL decoding, which means encoded special characters won't be handled correctly.
For example, a query string like key=value%3D1%26extra (where value=1&extra is URL-encoded) would be incorrectly split. Consider using proper URL decoding or a URL parsing library.

The asynchronous send(ICompleteListener) method signature in the IRequest interface declares throws HttpRequestException, but the new implementation never throws this exception. Instead, errors are logged but not propagated to the caller through the exception mechanism.
This is a behavior change from the previous implementation and could mask errors for code that relies on exception handling.

The previous Jetty implementation registered a shutdown hook to properly stop the HttpClient on application shutdown. The new implementation doesn't include any cleanup code for the WebClient or WebClientSession.
While Vert.x resources are typically managed by the Vert.x instance itself, it's good practice to explicitly close the WebClient and WebClientSession when the application shuts down to prevent potential resource leaks. Consider adding a @PreDestroy method or observing Quarkus shutdown events to call webClientSession.close() and webClient.close().

[nitpick] The code calls response.bodyAsString() on line 205 after already checking the body buffer. However, when body is not null but empty (length 0), this will still call bodyAsString(). While this may not be a critical issue, it's more efficient to use body.toString() directly or check if the body is empty before calling bodyAsString().
Additionally, consider that bodyAsString() uses the charset from the Content-Type header by default, which may be the desired behavior but differs from how the body buffer encoding was checked on line 192.

The HttpRequest object from Vert.x is mutable and the same request instance is reused in both doSend() calls (for synchronous and asynchronous send). If a user calls send() multiple times on the same RequestWrapper instance, the second call would fail because Vert.x HttpRequest instances are not reusable after being sent.
Consider documenting this limitation or creating a new request for each send operation if the interface contract allows request reuse.

21-29: Clarify or retire unused HTTP client configuration parameters
provideHttpClient(...)still accepts several Jetty-era config parameters that are no longer applied:
maxConnectionsQueuedrequestBufferSizeresponseBufferSizedisableWWWAuthenticationValidationOnly
maxConnectionPerRoute,maxRedirects,idleTimeoutInMillis, andconnectTimeoutInMillisare currently mapped intoWebClientOptions.Leaving these unused parameters in the producer signature can mislead users into thinking they still affect behavior. Either:
- remove them from the method (and update config/docs accordingly), or
- explicitly document them as no-ops/deprecated so it’s clear they’re ignored in the Vert.x-based implementation.

148-151: Preserve the interrupt flag in synchronoussend()In
send()theInterruptedExceptionis caught and wrapped inHttpRequestExceptionwithout restoring the thread’s interrupt status, which can break cooperative cancellation in calling code.You can restore the flag with a small change:

78-101:setBasicAuthenticationignoresrealmandpreemptiveflagsThe
setBasicAuthenticationimplementation:request.basicAuthentication(username, password);drops the
realmandpreemptiveparameters, which is a behavioral change from the Jetty version that could honor those flags. If callers depend on non-preemptive auth or realm-specific behavior, this may break interoperability.At minimum, document this limitation in the interface or method Javadoc; if realm-based or non‑preemptive auth is required, you may need to construct the
Authorizationheader manually according to the server’s expectations.
133-145: Max response size is enforced post‑hoc and can still exhaust memoryThe
setMaxResponseSizecomment says Vert.x “just buffers” and suggests the limit is mostly advisory, yetdoSendnow fails the handler whenbody.length() > maxLength. Two issues:
Comment vs behavior mismatch – the comment implies “warning / buffer handles it,” but the code actually treats exceeding
maxLengthas a hard failure (failedFuture(new IResponse.HttpResponseException(...))). The comment should be updated to match this behavior.Memory protection regression vs Jetty – Vert.x WebClient will still buffer the entire response body into memory before
body.length()is checked. For very large responses this can still lead to excessive memory usage or OOM, whereas Jetty’sBufferingResponseListener(maxLength)stopped buffering once the limit was hit.Short term, I recommend:
- Aligning the comment with the actual post‑hoc failure behavior.
- Explicitly documenting that this is a logical size guard, not a streaming cap.
Longer term, if you need real memory protection, consider a streaming approach (e.g. Vert.x core
HttpClientwith manual byte counting, or aBodyCodec.pipeoption) to stop reading oncemaxLengthis exceeded.Also applies to: 172-201
153-170: Asyncsend(ICompleteListener)never signals failures; fix callback behaviorCurrently:
send()(sync) correctly surfaces failures viaHttpRequestException(throughfuture.completeExceptionally).send(ICompleteListener)logs errors in theelsebranch ofdoSendbut never invokescompleteListenerwhen the request fails (network error, timeout, maxLength violation). Async callers can hang indefinitely waiting for a callback that never comes.You should ensure the listener is always invoked, even on failure. One pragmatic approach is to construct a synthetic error response:
public void send(final ICompleteListener completeListener) { - doSend(ar -> { - if (ar.succeeded()) { - try { - completeListener.onComplete(ar.result()); - } catch (IResponse.HttpResponseException e) { - log.error(e.getLocalizedMessage(), e); - } - } else { - log.error(ar.cause().getLocalizedMessage(), ar.cause()); - } - }); + doSend(ar -> { + IResponse response; + if (ar.succeeded()) { + response = ar.result(); + } else { + log.error(ar.cause().getLocalizedMessage(), ar.cause()); + ResponseWrapper errorResponse = new ResponseWrapper(); + errorResponse.setHttpCode(0); + errorResponse.setHttpCodeMessage(ar.cause().getMessage()); + errorResponse.setContentAsString(""); + errorResponse.setHttpHeader(Collections.emptyMap()); + response = errorResponse; + } + + try { + completeListener.onComplete(response); + } catch (IResponse.HttpResponseException e) { + log.error(e.getLocalizedMessage(), e); + } + });If the API contract prefers explicit error signaling, an alternative is to extend
ICompleteListenerwith an error callback, but the key point is: async callers must not be left without any completion signal on failure.Also applies to: 172-218, 254-267

There was a problem hiding this comment.
The idleTimeout conversion logic may lose precision for timeout values between 1 and 999 milliseconds. For example, an idleTimeout of 500ms would be converted to 0 seconds, then adjusted to 1 second (doubling the intended timeout). Consider documenting this behavior or using a more precise conversion that preserves the millisecond granularity if Vert.x supports it, or at least warning users about this limitation in configuration documentation.

The maximum response size validation has a potential issue: it checks Content-Length header and actual body length, but if the header is missing or incorrect, a large response could still be buffered entirely in memory before the check on line 206 is performed. For true protection against large payloads, consider using Vert.x's streaming API with byte counting to abort downloads that exceed the limit, rather than buffering the entire response first.

Misleading comment: The comment on line 177 says "Use stream to handle large responses safely" but the implementation doesn't use streaming. It still buffers the entire response in memory. Consider either updating the comment to reflect the actual behavior, or implementing true streaming if memory safety for large responses is a concern.

Behavior change in error handling: When the HTTP request fails (e.g., network error, timeout), the code creates a synthetic HTTP 500 response (lines 276-280) instead of propagating the error. This may mask the actual error type and make it harder for callers to distinguish between server errors (actual 500 responses) and client-side failures (network issues). Consider documenting this behavior or using a different status code (e.g., 503 for network issues) to differentiate error sources.

The configuration property httpClient.maxConnectionsQueued is no longer used after migrating to Vert.x but still exists in application.properties (line 13). Similarly, httpClient.requestBufferSize, httpClient.responseBufferSize, and httpClient.disableWWWAuthenticationValidation are no longer consumed. Consider documenting which configuration properties are deprecated or removing them from the configuration file to avoid confusion.

The realm and preemptive parameters are ignored in the Vert.x implementation of basic authentication. While there's a comment explaining this, the implementation always sends credentials preemptively. This is a behavior change from the Jetty implementation which could handle non-preemptive authentication (waiting for 401 challenge). This breaking change should be documented, or non-preemptive authentication should be implemented using a different approach if needed.

Potential redundancy: response.body() is called on line 205 and stored in body, then response.bodyAsString() is called on line 215. Since body is already available as a Buffer, consider using body.toString() instead of response.bodyAsString() to avoid potentially re-reading the body. This may also ensure consistency between the size check and the actual string conversion.

Missing timeout on blocking call: The synchronous send() method uses future.get() without a timeout parameter (line 167). If the Vert.x request timeout fails to trigger for any reason, this could block indefinitely. Consider using future.get(timeout, timeUnit) with a reasonable timeout value, possibly based on the timeout set via setTimeout(), to prevent indefinite blocking.

Missing resource cleanup: The old Jetty implementation had a shutdown hook to properly stop the HttpClient (removed code at lines 55-72 in the original). The new Vert.x implementation doesn't have any cleanup for the WebClient or WebClientSession. Consider adding a @PreDestroy method to close the WebClient and WebClientSession when the bean is destroyed to prevent resource leaks.

The requestEncoding is treated as a charset name string in Buffer.buffer(requestBody, requestEncoding), but if the encoding is invalid or unsupported, this could throw an uncaught exception. The Jetty implementation used Charset.forName(encoding) which would also throw but was more explicit. Consider wrapping this in a try-catch to provide a better error message, or validating the encoding when it's set in setBodyEntity().
| Buffer buffer = requestEncoding != null ? Buffer.buffer(requestBody, requestEncoding) : Buffer.buffer(requestBody); | |

- HttpClientModule: Added disposer method to close WebClient on destruction. - HttpClientWrapper: - Updated buffering vs streaming comments. - Wrapped encoding buffer creation in try-catch. - Implemented timeout for synchronous send() to prevent indefinite blocking. - Changed error response status from 500 to 503 (Service Unavailable). - Documented ignored Basic Auth parameters (realm, preemptive).

When wrapping exceptions from ExecutionException, the code loses the root cause information by calling e.getLocalizedMessage(). This can make debugging difficult since ExecutionException is just a wrapper. Consider using e.getCause() to get the underlying exception, e.g., Throwable cause = e instanceof ExecutionException ? e.getCause() : e; throw new HttpRequestException(cause.getLocalizedMessage(), cause); This would preserve the actual exception that occurred during the async operation.

The dispose method only closes the WebClientSession but doesn't close the underlying WebClient that was created on line 43. According to Vert.x documentation, both the session and the base WebClient should be closed to properly release resources. Consider also closing the base WebClient or storing a reference to it in VertxHttpClient for proper cleanup.

The query parameters from the URI are parsed manually on lines 85-94 but they're not URL-decoded. If the URI contains encoded query parameters (e.g., key=hello%20world), they will remain encoded in the queryParamsMap. Consider using URLDecoder.decode() to properly decode both keys and values when parsing the query string.

The comment on line 289 has a grammatical error: "strictly speaking" should be capitalized as it starts a sentence. It should read "Strictly speaking, ICompleteListener expects a response."

The idle timeout conversion from milliseconds to seconds has potential issues. When idleTimeout is between 1 and 999 milliseconds, the result will be 0, which is then changed to 1 second on line 35. However, when idleTimeout is exactly 0, it bypasses the check and sets the timeout to 0 seconds. This inconsistency could cause unexpected behavior. Consider handling the conversion more consistently: if the input is > 0 but < 1000, round up to 1 second; if it's 0, keep it as 0 (which typically means no timeout).

The field requestContentType is stored but never used. It's set in setBodyEntity but not referenced anywhere else in the code. Consider removing this unused field if it's not needed for future functionality.

The comments on lines 139-146 are excessively verbose and contain internal deliberation ("For now, we will assume...", "Actually, as(BodyCodec.string()) or similar doesn't limit"). These should be condensed to a concise explanation of what the implementation does and any known limitations, e.g., "Note: Vert.x WebClient buffers the entire response by default. Size limits are validated in handleResponse() after the response is received."

The comment states that 'realm' and 'preemptive' parameters are ignored, but this is a change in behavior from the previous Jetty implementation which supported non-preemptive authentication. This could be a breaking change for users who relied on non-preemptive basic authentication (preemptive=false). Consider documenting this breaking change more prominently or implementing a workaround if non-preemptive auth is required.

The HttpRequest<Buffer> object is mutable and shared across multiple method calls that modify it (e.g., putHeader, addQueryParam, timeout). If the same RequestWrapper instance is reused and send() or send(ICompleteListener) is called multiple times, the request will accumulate headers and query parameters from previous calls, leading to incorrect behavior. Consider either: 1) documenting that RequestWrapper should not be reused after sending, or 2) cloning/recreating the request for each send operation to ensure idempotency.
- HttpClientModule: - Store and close the underlying WebClient to ensure proper resource management. - Improve idle timeout conversion logic (use ceil for milliseconds). - HttpClientWrapper: - Unwrap ExecutionException to expose root cause. - URL-decode query parameters during parsing. - Remove unused requestContentType field. - Clarify and condense comments regarding buffering and Basic Auth limitations. - Add warning about non-reusability of RequestWrapper. - VertxHttpClient: - Added field to hold underlying WebClient.
Migrated the HTTP client implementation from Jetty Client to Vert.x Web Client.
This involved:
pom.xmlto replacejetty-clientwithvertx-web-client.getCookieStore()fromIHttpClientas it is not directly supported in the same way and wasn't widely used.VertxHttpClientto hold the Vert.x instance and WebClient.HttpClientModuleto configure the WebClient options (mapping pool size, timeouts, etc.) and produce theVertxHttpClientbean.HttpClientWrapperto useWebClientfor request building and execution. It supports both synchronous (blocking) and asynchronous execution modes, preserving the existing interface contracts.CompletableFutureis used to bridge the async Vert.x API to the synchronoussend()method.PR created automatically by Jules for task 9619466246744998612 started by @ginccc
