[jboss-jira] [JBoss JIRA] Closed: (JBTM-216) Contention on Vector _threadSetups in ThreadActionData.java

[Mark Little (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBTM-216?page=all ]

Mark Little closed JBTM-216.
----------------------------

    Fix Version/s: 4.2.3.SP3
       Resolution: Done

The datastructure didn't need to be synchronized on use, only on modification. The assumption was already there that additions and removals to the structure happen before the system starts or after it has shutdown, respectively. So we've changed this to an unsynchronized item except for additions/removals.
