Smoke tests hang in management request handling code
----------------------------------------------------

                 Key: JBAS-9042
                 URL: https://issues.jboss.org/browse/JBAS-9042
             Project: JBoss Application Server
          Issue Type: Bug
      Security Level: Public (Everyone can see)
          Components: Domain Management
            Reporter: Brian Stansberry
            Assignee: Brian Stansberry
            Priority: Blocker


I'm seeing hangs in the smoke tests where threads are all blocking in the management request handling code. Thread dump attached.

One thing that stands out is the large number of threads in this state:

"pool-1-thread-7" prio=5 tid=102be5800 nid=0x10f377000 in Object.wait() [10f376000]
   java.lang.Thread.State: WAITING (on object monitor)
	at java.lang.Object.wait(Native Method)
	- waiting on <7f5235be8> (a java.lang.Object)
	at java.lang.Object.wait(Object.java:485)
	at org.jboss.as.protocol.Pipe$1.read(Pipe.java:75)
	- locked <7f5235be8> (a java.lang.Object)
	at org.jboss.as.protocol.ConnectionImpl$MessageInputStream.close(ConnectionImpl.java:302)
	at org.jboss.as.protocol.StreamUtils.safeClose(StreamUtils.java:294)
	at org.jboss.as.protocol.mgmt.AbstractMessageHandler.handleMessage(AbstractMessageHandler.java:65)
	at org.jboss.as.protocol.ConnectionImpl.safeHandleMessage(ConnectionImpl.java:254)
	at org.jboss.as.protocol.ConnectionImpl$1$1.run(ConnectionImpl.java:213)
	at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)
	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)
	at java.lang.Thread.run(Thread.java:680)

I don't see how there would be that many concurrent requests going on; what I *suspect* is happening is those threads are handling requests from different test cases and are hanging. Eventually the pool is exhausted.
