Aias00 opened a new issue, #6737: URL: https://github.com/apache/shenyu/issues/6737
- severity: Medium - files: `shenyu-plugin/shenyu-plugin-proxy/shenyu-plugin-rpc/shenyu-plugin-tars/src/main/java/org/apache/shenyu/plugin/tars/cache/ApplicationConfigCache.java:189-206` - description: `initPrx` is a `while(true)` loop that calls `tryLockedLoadMetaData(...)` whenever `prxClassCache.get(path)` is null. `tryLockedLoadMetaData` uses `LOCK.tryLock()`; if the lock is held, it returns immediately, leaving `prxClass` null, so the loop re-enters with no `Thread.yield()`/backoff. - impact: Under concurrent tars metadata registration, worker threads spin-wait (100% CPU) for the duration of ByteBuddy class generation. - suggested_fix: Acquire the lock blockingly inside the loop, or back off with `Thread.yield()` when `tryLock()` fails. - confidence: Medium - related_existing: none --- _Identified during the 2026-08-02 deep re-scan; full list in [`docs/scan2-2026-08-02/06-medium-tiers.md`](docs/scan2-2026-08-02/06-medium-tiers.md)._ -- This is an automated message from the Apache Git Service.
