[jboss-jira] [JBoss JIRA] Commented: (JBAS-7114) Undeploy-deploy loop of directly referenced applications due to hasStructureBeenModified

[Ales Justin (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-7114?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12477050#action_12477050 ] 

Ales Justin commented on JBAS-7114:
-----------------------------------

We need to identify deployments somehow, and path name (relative path from root to deployment) was a logical choice.
Perhaps a workaround would be to have filter on the value + have root at file://home/.

But I see I need to re-think this mechanism, as your use case is valid.
Similar use case would be two exactly same named deployments in two different profile folders.
e.g. home/app.jar and deploy/app.jar, where home/ and deploy/ are roots
