If 'closeImmediately' in this line:
CloseFuture closeFuture = getSession().close(closeImmediately);
resolves to false, I have observed Mina to leave behind a couple threads
in WAIT states that in my experience never came out of that state. In
my case, changing the getSession().close(false) to
getSession().close(true) stopped that problem dead in its tracks.

telnet session I am testing with remains open). Additionally, I
still see a
couple of MINA-related threads running (and NioProcessor thread & some
thread-pool threads).
What am I missing? Am i going about this the wrong way?

I basically do shutdown same as you. Only difference is that I close
the open session first:
public class ShutdownCommand extends TextProtocolCommand {
...
public ProtocolResponse execute() throws Exception {
...
CloseFuture closeFuture = getSession().close(closeImmediately);
closeFuture.addListener(new CloseSessionListener());
return null;
}
...
class CloseSessionListener implements IoFutureListener<CloseFuture> {
public void operationComplete(CloseFuture future) {
getServerControl().shutDown();
}
}
}
public class CacheServer implements CacheServerControl {
...
public void shutdown() {
logger.debug("{} protocol processor shutting down server
socket", protocolType);
protocolAcceptor.unbind();
protocolAcceptor.dispose();
}
private String protocolType;
private SocketAcceptor protocolAcceptor;
private Logger logger;
}
Maybe try doing a thread dump and see where in the code the remaining
threads are hanging.
