**Issue Evaluation** Category: `type/bug` | Status: **Confirmed** The reported issue has been verified against the current codebase (`develop@eddb235c1bd8`). **Root Cause:** `ClusterMessageService.batchAckMessage(...)` calls `handleList.get(0)` at line 164 without checking if the list is empty. When `handleList` is empty, this throws `IndexOutOfBoundsException`. **Impact:** Batch ack operations fail with an uncontrolled exception when no handles are provided. **Severity:** medium — requires an empty handle list to trigger, but the failure is uncontrolled. **File:** `proxy/src/main/java/org/apache/rocketmq/proxy/service/message/ClusterMessageService.java` (lines 159-168) An automated fix proposal will be generated.
