**Issue Evaluation** Category: `bug` | Status: **Confirmed** The reported issue has been verified against the current codebase. **Root Cause:** `RealClusterProvider.toClusterVOs` calls `sorted(Map.Entry.comparingByKey())` on the `clusterAddrTable` entry set. A null cluster name key triggers NPE in the comparator. Additionally, `entry.getValue()` can be null (a cluster with no broker-name set), causing NPE when `.stream()` is invoked. **Impact:** Cluster discovery fails entirely when any NameServer response contains malformed topology entries, hiding valid clusters from Studio. **Severity:** medium An automated fix proposal will be generated.
