> Under specific conditions the STOMP server continues to execute the heartbeat runnable task
even after the client connection has closed.  In the extreme case this can result in eventual
server failure since a new StompConnection and associated scheduled task are kept in memory
indefinitely and a new one is created each time a client connects.  Therefore if a client
repeatedly connects and triggers the error in a loop, eventually the server will run out of
resources.
> The condition occurs when using STOMP 1.2, if a client sends a duplicate subscription
ID.  The server correctly sends an ERROR frame to the client and closes the connection, but
does not properly clean up the heartbeater which continues to run indefinitely according
to the defined interval, even though there is no client to respond.
> See the attached integration test for details.  (This is a modified version of an existing
test for a similar issue that was fixed for version 1.5.3).  The test code is src/test/java/org/apache/artemis/tests/integration/stomp/v11/StompV11Test.java.
