[infinispan-issues] [JBoss JIRA] Resolved: (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: biggest_leakers.zip, infinispan_leak.zip During an execution of a test suite TestNG keeps references to all executed test class instances. Some of our test classes keep references to instantiated caches, cache managers, and other heavy weight objects thus preventing those references from ever being garbage collected. Our test classes should *never* keep references to heavyweight objects other than in a test method scope. If we must keep reference to a cache or a cache manager in a class scope these references should be cleared and nulled in a method annotated with @AfterClass. Since TestNG does not traverse class hierarchy for invocation of @AfterClass annotated methods we have to ensure that every @AfterClass method is invoked in test class hierarchy (i.e call super).
