             Summary: L1WriteSynchronizer can cause locking with concurrent gets when value is not present
                 Key: ISPN-3956
                 URL: https://issues.jboss.org/browse/ISPN-3956
             Project: Infinispan
          Issue Type: Bug
            Reporter: William Burns
            Assignee: Mircea Markus


This has been seen previously only on IBM JDK 6 ISPN-3889, however an end user also now can reproduce this issue https://community.jboss.org/thread/236590

The issue is that we don't set the remove lookup value to be null when nothing is found and thus any threads that are waiting for the remote lookup were never notified of this.
