Michael, try this one:
public void stop() {
logger.log(InternalLogLevel.INFO, this.getClass().getSimpleName()
+ " start stop");
this.channel.close().awaitUninterruptibly();
NettyKarmaReceiver.this.factory.releaseExternalResources();
logger.log(InternalLogLevel.INFO, this.getClass().getSimpleName()
+ " end stop");
}
If you block in the Netty thread, then the close operation is never
finished, and the terminate() call is in an endless loop, resulting in a
deadlock. Either you do it outside the Netty thread as above, or you
create a new Thread and run it there.
