To track this, I temporary added this to KafkaManager.releaseSub():
LOGGER.info("releaseSub: timeout=" + timeout + " " + timeUnit.toString(), new
Throwable());
and I get:
2016-09-28 17:43:14,382 pool-1-thread-1 INFO releaseSub: timeout=0

at java.lang.Thread.run(Thread.java:745)
the culprit is AbstractLifeCycle.stop() which uses a default timeout of 0.
