Pretty simple test to reproduce the cause of the issue. @Test
void writePathRecursively() {
writePath(Path.of("a"));
}
void writePath(Path path) {
System.out.println(path.toString());
path.forEach(this::writePath);
}a

Prior to this commit, serializing `java.nio.file.Path` caused a StackOverflowError because `Path.iterator()` always returns itself as the first element of the iterator, which results in a StackOverflowError. This commit serializes `java.nio.file.Path` as JSON String. Signed-off-by: Dmytro Nosan <[email protected]>
