    You must have root authority to install this fileset.
     - Download jtkaix.tar into a directory.
     - Extract the fileset using the command "tar -xvf jtkaix.tar".
     - Start "smit install_update".
     - Select "Install/Update From All Available Software".
     - Enter the directory name to which the fileset was extracted.
     - Enter the fileset name, cpjtk.obj,
         into the field "SOFTWARE to install".
 
    Service files are installed with root ownership and root access permissions.
    If you want users WITHOUT root authority to be able to start or access the
    IBM Enterprise Toolkit for Java Technology Edition product files,
    the following changes are required:
     - Change the group with the chgrp command for all of the
       directories and files within the installation path.
       For example, to permit the Admin group, issue:
         "chgrp -R Admin /usr/lpp/cseb"
     - Change the file permissions with the chmod command.

    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.

    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.

    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.
