Bela Ban commented on JGRP-526:
-------------------------------

Interrupting the thread does the job, this needs to be done in stop()

> When stopping the perf.Test, one thread in CT is still running (stack trace below). This is also the reason for the unit test failure in ConnectionTableTest.
> The thread calls take() on a LinkedBlockingQueue, and the stop() method calls queue.clear() to terminate the thread, but apparently that's not the case.
> Solution: find out what terminates take() and call it in stop().
