[jboss-jira] [JBoss JIRA] (WFLY-5439) Data Race accessing org/jboss/dmr/ModelNode.value

[Brian Stansberry (JIRA)]

     [ https://issues.jboss.org/browse/WFLY-5439?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Brian Stansberry resolved WFLY-5439.
------------------------------------
    Resolution: Rejected


The AbstractControllerService$1 thread ensures the ParallelBootTask has completed before proceeding to the done stage. During all of this the AbstractControllerService$1 thread has its own copy of the model that it only make visible to the threads running the ParallelBootTasks.
