[infinispan-issues] [JBoss JIRA] Updated: (ISPN-220) Test suite has memory leaks

Test suite has memory leaks --------------------------- Key: ISPN-220 URL: https://jira.jboss.org/jira/browse/ISPN-220 Project: Infinispan Issue Type: Bug Affects Versions: 4.0.0.BETA2 Reporter: Vladimir Blagojevic Assignee: Vladimir Blagojevic Fix For: 4.0.0.CR1 Attachments: infinispan_leak.zip TestNG during an execution of a test suite keeps references to all executed test class instances. Our test classes in some cases keep references to instantiated caches thus preventing cache instances from ever being garbage collected. Our test classes should never keep references to cache instances other than in a test method scope. If truly there is a need to keep reference to a cache in a class scope these references should be cleared and nulled in a method annotated with @AfterClass. Of course, the same applies to any objects in class scope (cache managers etc etc.) Since TestNG does not traverse class hierarchy for invocation of @AfterClass annotated methods a special care has to be taken that every @AfterClass method is invoked in test class hierarchy (i.e call super).
