The javadoc of javax.management.remote.JMXConnector#connect says that "If connect has already been called successfully on this object, calling it again has no effect.".
But this does not work with org.jboss.remotingjmx.RemotingConnector. Every connect result in a creation of a remoting endpoint with the corresponding io/worker threads, which are not closed when close() method is called. Only the threads from the first connect() invocation are closed, all threads created from the subsequent connect() invocations are not closed and stay alive until the VM shutdown.
Our application currently crashes after 10 minutes running - it pulls some JMX data periodically and after some time, the VM refuses to create new threads.
