Date Wed, 29 Aug 2007 23:32:30 GMT
Concurrency issuses in the nexus partition lead to race conditions with unbind requests on
shutdown.
----------------------------------------------------------------------------------------------------

                 Key: DIRSERVER-1047
                 URL: https://issues.apache.org/jira/browse/DIRSERVER-1047
             Project: Directory ApacheDS
          Issue Type: Bug
            Reporter: Alex Karasulu
             Fix For: 1.5.2


Getting the following stack trace when there is a race condition with server shutdown and
an unbind request which tries a getPartition when the partitionTree has been emptied out.
