During a CHO test, one broker crashed with a NPE. We lost the logs due to a cleanup of files, but we have the general stack trace:
managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/EntryImpl.java: 132: return data.readableBytes();
managed-ledger/src/main/java/org/apache/bookkeeper/mledger/impl/EntryCacheImpl.java: 115: manager.entryAdded(entry.getLength());
