**Issue Evaluation** Category: `bug` | Status: **Confirmed** The single-master probe in `RocketMQLiteTopicProvider.isSupported()` is a legitimate availability issue. Checking only `masters.get(0)` means a transient failure or version mismatch on that one broker disables the entire LiteTopic feature for the cluster. **Root Cause:** No iteration or fallback when the first master is unreachable or pre-lite; exception is swallowed and capability is reported as false. **Impact:** Mixed-version clusters or rolling upgrades incorrectly report LiteTopic as unsupported; transient broker failures cause feature degradation. **Severity:** High (feature availability in production clusters) Fix PR #4568 is already submitted. The issue includes clear code references and impact analysis. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
