[jboss-jira] [JBoss JIRA] (WFCORE-1049) ConcreteResourceRegistration#registerSubModel is not thread safe

[Brian Stansberry (JIRA)]

    [ https://issues.jboss.org/browse/WFCORE-1049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13117388#comment-13117388 ] 

Brian Stansberry commented on WFCORE-1049:
------------------------------------------

Per our chat in the hallway, I think the issue is more that the MRR is registered (and is thus visible to other threads) before the rest of the initialization work is completed. Stuff like registerAttributes, registerOperations, registerChildren.

> registerSubModel checks for existing, then registers, however it is invoked by two threads at the same time it is possible they will both see the resource as not existing and both register.
