Adrian Brock commented on JBAS-5368:
------------------------------------

The issue here is that the ClassLoadingDomain for the war has the ear classloader as a parent.

When it undeploys the ear it should remove this domain. Otherwise when you redeploy
you end up using the ear classloader from the previous deployment which has been undeployed.

> Just copying an ear with a war (testsuite/output/lib/form-auth.ear) twice to the server deploy directory results in a failure like the following. All subsequent copy/redeployment attempts fail in the same way.
