             Summary: DefaultThreadFactory: newThread() names a thread twice
                 Key: JGRP-1719
                 URL: https://issues.jboss.org/browse/JGRP-1719
             Project: JGroups
          Issue Type: Enhancement
            Reporter: Bela Ban
            Assignee: Bela Ban
             Fix For: 3.5


DefaultThreadFactory.newThread() creates a new thread with a name, but then calls renameThread(). 
This effectively names the thread *twice*, which is means the cost of thread creation is higher than  it should be (naming involves calling {{SecurityManager.checkAccess()}}.
SOLUTION:
Prepare the name *before* creating the thread and then pass the name to the constructor.
