JDT.LS fails to start with "Unrecognized VM option 'AllowArchivingWithJavaAgent'" #4511
Describe the bug
When running vscode-java pre-release, with Java 26 (I haven't touched Java in ages), in vscode insiders, the server fails to start:
2026-09-23 15:41:54.784 [error] Unrecognized VM option 'AllowArchivingWithJavaAgent' []
2026-09-23 15:41:54.784 [error] Error: Could not create the Java Virtual Machine. []
2026-09-23 15:41:54.784 [error] Error: A fatal exception has occurred. Program will exit. []
The AllowArchivingWithJavaAgent option was removed a year ago: openjdk/jdk@000569d
