JBoss Deadlock in org.jboss.util.NestedThrowable

Environment

• JBoss Application Platform (EAP)
  • 4.2
  • 4.3

Issue

• JBoss becomes unresponsive. Checking thread dumps, it looks like there could be a deadlock as multiple threads are stalled up in the initialization of org.jboss.util.NestedThrowable or its Utils subclass:
