[Brian Stansberry (JIRA)]

     [ https://jira.jboss.org/jira/browse/JBAS-7379?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Stansberry resolved JBAS-7379.
------------------------------------

    Fix Version/s: JBossAS-5.2.0.Beta1
                   JBossAS-6.0.0.Alpha1
       Resolution: Done


Fixed on Branch_5_x and trunk.

Dennis, if you port this to the EAP branches, be aware that a previous commit (r 95441 on Branch_5_x) rearranged some classes in the testsuite. You'll need to port that as well to get the test to compile.
