Subject [jira] [Created] (CONNECTORS-1126) Lock manager's lock ordering not working as designed

---------------------------------------

             Summary: Lock manager's lock ordering not working as designed
                 Key: CONNECTORS-1126
                 URL: https://issues.apache.org/jira/browse/CONNECTORS-1126
             Project: ManifoldCF
          Issue Type: Bug
          Components: Framework core
    Affects Versions: ManifoldCF 1.7.2
            Reporter: Karl Wright
            Assignee: Karl Wright
             Fix For: ManifoldCF 1.9, ManifoldCF 2.1


The LockGate logic for flushing a LockGate is as follows:

{code}
    synchronized (lockObject)
    {
      if (lockObject.leaveReadLock())
      {
        if (lockPool != null)
          lockPool.releaseObject(lockKey, this);
      }
    }
{code}

Unfortunately, this has the side effect of causing the nicely build thread queue to be destroyed
on the first time a lock is exited.  That kills ordering and makes LockGate essentially do
nothing of value.
