        Type: Bug
  Components: framework  
    Versions: 1.1    
 Environment: HiveMind 1.1-alpha-3

Occasionally my Tapestry applications seem to lock up.  Just happened when I was in the debugger
and I was able to pause and see what the contention is.

 private synchronized void checkShutdown()
    {
        if (_shutdown)  // Line 345
            throw new ApplicationRuntimeException(HiveMindMessages.registryShutdown());
    }

Are the only threads in the application anywhere near HiveMind. 

Unfortunately, I was running with JDK 1.4, so I can't use Eclipse's debugger to get at threads
and monitors.

This is something that needs more attention ... and I can't see how they would be conflicting.
