Description

There are only add-element operations for waitingThreadTable in Class org.apache.rocketmq.store.ha.WaitNotifyObject.

Each time a new thread calls Method WaitNotifyObject#allWaitForRunning, waitingThreadTable get new element.

This leak actually happens in Master Broker when Slave reconnect to the Master, a new HAConnection is created, and WaitNotifyObject#allWaitForRunning will be called in LogHAConnection.WriteSocketService#run.
