                 URL: http://jira.jboss.com/jira/browse/JBAS-5079
             Project: JBoss Application Server
          Issue Type: Feature Request
      Security Level: Public (Everyone can see)
          Components: Other
    Affects Versions: JBossAS-4.2.2.GA
            Reporter: Jay Howell


Many Other application servers have a stuck thread reaper that looks at threads and the times that they have been taking.  If they take too long they are either logged as a warning or they are killed.  This is a very dangerous safeguard, but it's a feature that does come in quite handy if a thread gets stuck on an object lock.  We've seen some of these in support especially around the Jbosscache when customers misconfigure JbossCache with ejb3/hibernate.  It also happens with customers do strange things with jms inside the app server. 

The configuration might be something like.
StuckThreadInterval - interval at which the scanner should scan for stuck threads.  Higher amounts will give more time before the event(log or inturrupt) is fired. -1 means it's disabled.
StuckThreadNotification - class to be called if a thread gets stuck default would be org.jboss....StuckThreadLogger

the default behavior should log the stuck thread.

But we should also have another class that can be plugged in the StuckThreadNotification that inturrups the thread.  Maybe we can call it org.jboss.....StuckThreadInturrupter
Log should always log it, but with a configuration change, it should be able to inturrupt it.

We've had multiple requests for this feature.
