**Issue Evaluation** Category: `bug` | Status: **Confirmed** The unhandled `UndeclaredThrowableException` wrapping `MQLiteRequestException` is a legitimate error-handling bug. When one broker master fails, the exception propagates uncaught and causes a 502 for the entire LiteTopic list/quota pages instead of degrading gracefully. **Root Cause:** Missing exception handler for `UndeclaredThrowableException` in the lite topic list/quota endpoints; the wrapped `MQLiteRequestException` is not extracted and handled. **Impact:** Single broker failure causes complete page failure (502) instead of partial degradation; poor user experience during broker issues. **Severity:** High (availability degradation) Fix PR #4566 is already submitted. The issue includes stack traces and clear reproduction steps. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
