Here is related code: {code} public void restoreState(SerializedCheckpointData[] state) throws Exception { synchronized (pendingCheckpoints) { pendingCheckpoints = SerializedCheckpointData.toDeque(state, idSerializer); {code} When lock is held on current pendingCheckpoints field, new reference is assigned to the same field - making the synchronization ineffective. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
