JCacheConfigurationTest leaks cache manager ------------------------------------------- Key: ISPN-10880 URL: https://issues.jboss.org/browse/ISPN-10880 Project: Infinispan Issue Type: Bug Components: Test Suite - Core Affects Versions: 10.0.0.Final Reporter: Dan Berindei Assignee: Dan Berindei Priority: Major Labels: testsuite_stability Fix For: 10.1.0.Beta1 {noformat} ThreadLeakCheckerorg.infinispan.commons.test.ThreadLeakChecker$LeakException: Leaked thread: expiration-thread--p446-t1 << testng-JCacheConfigurationTest << org.infinispan.jcache.JCacheConfigurationTest ...

The threads created by {{DefaultCacheManager}} ensure it's still referenced during finalization, allowing it to stop cleanly.
