commit a03e15efe7ba2fe4b710a779078ba8a268deadc4 Author: Guillaume Nodet <[email protected]> AuthorDate: Fri Jun 19 08:36:38 2026 +0200 [#12301] Fix StackOverflowError with internal parent and CI-friendly revision Re-forward-port the GH-12301 fix from maven-4.0.x to master, using ThreadLocal<Set<Path>> instead of the shared ConcurrentHashMap.newKeySet() that caused a race condition with PhasingExecutor parallel model loading. The original forward-port (#12317) used a shared set to track which POM files were being read by doReadFileModel(). This prevented the StackOverflowError from GH-12301, but caused false cycle detection when parallel threads in loadFilePom() read the same model simultaneously — breaking ConsumerPomBuilderTest.testSimpleConsumer. The fix uses ThreadLocal so each thread tracks only its own call stack, preventing actual recursive cycles within the same thread without blocking legitimate parallel reads across threads.
