Exception thrown when shutting down

[Chris]

Hi - I have an app that launches a cluster on the fly, does
processing, and then shutdown down each node. With 1.9.4.8, I am
seeing exceptions thrown when shutting down, as shown here:

http://pastebin.com/A8q1E2QV

Basically, when each node detects that the jobs are finished, they
call Hazelcast.getLifecycleService().shutdown(). Nodes know when they
are done because they check, as follows:

while (Hazelcast.getSet(Sets.COLLAPSED_END.toString()).size() !=
files.size()) {
Thread.sleep(100)
}

Is this the right way to shutdown nodes? Is this some sort of race
condition which causes the exception to the thrown?

Thanks,
Chris

Yes, it is the right way shutting down HazelcastInstance. That error is related to unregistering jmx beans and fixed in version 2.0.
