    Library: 1695
    Symptom: Premature shutdown of provider
    Problem: If multiple LineResources are associated with the same JTAPI
             user and the LineResource.stop() method is invoked, the
             provider is shutdown, even if other LineResources still have
             observers.
   Solution: Only shutdown the provider when there are no more observers
             attached.

    Symptom: CEO Server failure not detected
    Problem: Assumption was that Java would throw exception in available
             when listening to a socket which fails. Exception was not
             generated so clean up code did not run. The result of this is
             any provider observers not getting notified of OUT_OF_SERVICE
             or SHUTDOWN.
   Solution: Added in function to allow the JTAPI client to start sending
             CallPath Enterprise heartbeat messages to the server any time
             the connection would otherwise be idle. If the heartbeats fail
             we assume the connection is lost, clean up and notify any
             interested provider observers.
 
       Name: APAR IC30895
       Date: 09 Jul 2001
    Library: 1691
    Symptom: Reuse Providers in bad state.
    Problem: In order to improve efficiency, the JtapiPeer was modified to
             reuse providers on getProvider() calls if the login arguments
             were the same. This change should have reused providers in any
             state except SHUTDOWN. Instead the client would reuse
             providers unless they were in state OUT_OF_SERVICE.
   Solution: Since we cannot reuse shutdown providers the selection
             criteria had to be changed to return OUT_OF_SERVICE providers
             but to create new providers if the provider was SHUTDOWN.
 
       Name: APAR IC30895
       Date: 09 Jul 2001
    Library: 1689
    Symptom: Endless recursion in LineResource.stop()
    Problem: It was possible for the client to get stuck in an endless
             recursion through the LineResource.stop() methods due to the
             subclass calling the superclass, which in turn called the
             subclass again.
   Solution: No longer allow the recursion to happen. Detect the condition
             which triggers the problem and end the recursion.
