[Manik Surtani (JIRA)]

     [ http://jira.jboss.com/jira/browse/JBCACHE-1165?page=all ]

Manik Surtani updated JBCACHE-1165:
-----------------------------------

        Summary: Endless loop in PessimisticLockInterceptor, sometimes seen as a NodeNotExistsException  (was: Endless loop in PessimisticLockInterceptor)
    Description: 
See ConcurrentPutRemoveTest

This sometimes manifests itself as an endless loop, and sometimes as a NodeNotExistsException (on the putter thread)  when concurrent puts and removes are involved.



  was:
When 2 Threads are simulatanous putting/removing values from this same node TreeCache hang's up and goes into endless loop.
Main loop looks like:
				for (int x = 0; x < 1000; x++) {
					tm.begin();
					System.out.println("R" + Thread.currentThread().getName());
					//inside transaction
					cache.remove("/a");
					System.out.println("AR" + Thread.currentThread().getName());
					tm.commit();
					//outside transaction
					System.out.println("P" + Thread.currentThread().getName());
					cache.put("/a/b/c/d", "text"+x,"b");
					System.out.println("AP" + Thread.currentThread().getName());
				}
