gnodet opened a new pull request, #12468: URL: https://github.com/apache/maven/pull/12468
## Summary Backport of #12446, which fixes #12445. Cherry-pick of squash-merge commit c6de104bff92fc0c4572813bac82935470441dc4 from `master` to `maven-4.0.x`. The fix replaces the wait/notify pattern in `AbstractRequestCache.requests()` with direct value setting via `CachingSupplier.complete()`, preventing deadlocks when re-entrant `requests()` calls occur (e.g., parent POM resolution during artifact resolution). It also adds `ThreadLocal` re-entrancy detection and `setBatchResolving()` so concurrent threads wait for in-progress batch results while same-thread re-entrant calls use a fallback supplier. Conflicts were resolved during cherry-pick (the 4.0.x branch had a `CyclicCacheAccessException`-based approach that was replaced by the new batch-resolution pattern). ## Test plan - [ ] CI passes on maven-4.0.x - [ ] `AbstractRequestCacheTest` passes (included in this backport) 🤖 Generated with [Claude Code](https://claude.com/claude-code) -- This is an automated message from the Apache Git Service.
