> In JMX client application, every JMXConnectorFactory#connect() invocation creates a new ThreadGroup which is never reclaimed.
> https://github.com/jbossas/remoting-jmx/blob/3.0.1.Final/src/main/java/org/jboss/remotingjmx/protocol/v2/ClientExecutorManager.java#L51
> If a JMX client application lives for long periods of time and repeats to invoke JMXConnectorFactory#connect() and JMXConnector#close(),  a lot of ThreadGroup instances are retained eventually.
