Dan Berindei commented on ISPN-8610:
------------------------------------

The {{ClientListenerNotifier}} executor that was causing this error was removed in 9.2.0 with the move to Netty.

However, the new {{ClientListenerNotifier}} now has a {{reconnectExecutor}}, which is used less often, but is not closed properly, and it is leaked in {{ClientListenerRemoveOnStopTest}}:
