[jboss-jira] [JBoss JIRA] Closed: (JBAS-2909) Testcase infra structure for MemoryLeaks

Testcase infra structure for MemoryLeaks ---------------------------------------- Key: JBAS-2909 URL: http://jira.jboss.com/jira/browse/JBAS-2909 Project: JBoss Application Server Issue Type: Feature Request Security Level: Public(Everyone can see) Components: Test Suite Reporter: Clebert Suconic Assigned To: Brian Stansberry Fix For: JBossAS-4.2.0.GA We could modify JBossTestCase::deploy to introspect every package being deployed and write details to a list. (say the name of the loaded classes, the name of the package and the name of the test). Later before stopping the server on the testsuite, we should introspect loaded classes on the server and compare to the list. The intersection should be zero. Also before doing such comparisson is a good idea to force an OutOfMemoryError, forcing eventual SoftReferences being released (e.g. JavaSerialization or any other Reflection cache) To load the list we could use -XX:PrintClassHIstogram with a kill -3 on the server, or JVMTIInterface from JBossProfiler could also give you such list (by using a couple of methods for that). This is an example of how to list loaded classes using JVMTIInterface from JBossProfiler: jvmtiInterface.forceReleaseOfGC(); Class[] classes = jvmtiInterface.getLoadedClasses();
