**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** NPE occurs when a consumer group has no subscription data but the system attempts to process consumer list operations. **Root Cause:** Missing null check on subscription data when building consumer group lists. **Impact:** Runtime crash when consumer groups are in an inconsistent state (e.g., during rebalancing or after all consumers disconnect). **Severity:** medium — affects operational stability during edge cases. A fix should add defensive null checks before accessing subscription data. --- *Automated evaluation by RockteMQ-AI* -- This is an automated message from the Apache Git Service.
