"Kevin.Conner(a)jboss.com"At which point was this reference graph produced?[/quote wrote : | | The test makes several independent calls on CMT session beans with default semantics, so for each call the tx should be committed on method exit. | | The test then undeploys the deployment. | | The graph is produced after the undeployment. Before it's produced numerous attempts to force release of a WeakReference to the classloader are made, so it's probably a good 15-20 seconds after the undeploy completes before the heap snapshot is taken.
