[jboss-jira] [JBoss JIRA] (JGRP-1719) DefaultThreadFactory: newThread() names a thread twice

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: 3.4.1, 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.
