[ https://issues.jboss.org/browse/ISPN-7598?page=com.atlassian.jira.plugin.... ] Dan Berindei commented on ISPN-7598: ------------------------------------ Found more leaked threads in the test suite: * {{SingleFileStoreStressTest}} creates some executors to run {{SingleFileStore.process()}} and never stops them. * {{ClusteredSecureCacheTest}} and {{CacheAuthorizationTest}} don't properly shut down the cache manager because of a NPE. * {{ParallelIteratorTest}} subclasses don't stop the executor service. * The {{CountingCARD}} used by some functional API tests doesn't shut down its timeout executor. The problem in {{ClusteredSecureCacheTest}} is that {{TestingUtil.killCacheManagers()}} first stops each cache individually, including the security cache, and only then calls {{DefaultCacheManager.stop()}}. {{DefaultCacheManager.terminate()}} then tries to unregister the cache MBeans from JMX, even if the cache is already stopped (because {{CacheJmxRegistration.stop()}} doesn't do that). But because the security cache is also stopped, {{unregisterCacheMBean}} throws a {{NullPointerException}}, and the cache manager doesn't shut down properly. {noformat} 12:10:03,334 WARN (testng-test:[]) [TestingUtil] Problems killing cache manager org.infinispan.manager.DefaultCacheManager@54cf7c6a@Address:test-NodeB-27841 org.infinispan.IllegalLifecycleStateException: ISPN000323: ___acl_cache is in 'TERMINATED' state and so it does not accept new invocations.
