## What problem does this PR solve? This fixes a potential Java deadlock caused by lock-order inversion between: - object monitor ( methods) - Caffeine/ConcurrentHashMap internal key locks during cache invalidation/loading The deadlock can happen when one thread holds the catalog monitor and invalidates cache, while another thread holds cache-internal lock and calls back into catalog initialization. ## What is changed? 1. In , split reset flow into: - lock-protected state reset () - cache refresh outside catalog monitor 2. In , keep identifier mapping reset under lock, but perform outside lock. 3. Add FE unit test to assert runs without holding catalog monitor (both base external catalog and JDBC external catalog path). ## Testing - Not rerun to completion in this turn after branch switch. -- This is an automated message from the Apache Git Service.
