Subject [jira] Commented: (GERONIMO-4543) EAR classloader not garbage collected
Date Thu, 19 Feb 2009 21:56:01 GMT

----------------------------------------

Hi Janko,
How many ClassLoader's are you seeing that aren't being GC'ed? Are you seeing OOME PermGen
errors? Or just noticing that some ClassLoader's aren't being GC'ed? Are multiple deploy/undeploy
cycles going to drive the problem? Or are you driving the app, also?

> The TransactionTimer$CurrentTime thread inherits the AccessControlContext of the first
EAR/WAR/EJB-jar that carries out a transaction. Thus, the particular EAR/WAR/EJB-jar's classloader
is prevented from being GCed.
