             Summary: Derby network server failed to shutdown
                 Key: DERBY-7044
                 URL: https://issues.apache.org/jira/browse/DERBY-7044
             Project: Derby
          Issue Type: Bug
          Components: Network Server
    Affects Versions: 10.14.2.0
            Reporter: Brett Bergquist
         Attachments: derby-0.log, stacktrace.txt

Derby network server failed to shutdown.  It was hung up and had to be killed manually.

See the stack trace and also the derby-0.log attached. 

It looks like it got stuck when a XA transaction was to be rolled back because the shutdown was done while one was in progress.  It was waiting on a condition:
{code:java}
