[Thomas Diesler (JIRA)]

    [ https://jira.jboss.org/browse/JBAS-8561?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12559938#action_12559938 ] 

Thomas Diesler commented on JBAS-8561:
--------------------------------------

The underlying cause is that the MountHandle attached to the DeploymentUnitContext is not associated with the DeploymentService
