Description:
Following are the defect fixes in TIBCO Integration Manager 5.0.1 hotfix3 -
    
     General Issues:
        * Defect Id :   1-19Z989
          Under heavy load, TCP Request/Reply task may throw "Invalid
          state - duplicate invocation attempt of task" error for
          some jobs and cause them to hang. This has been fixed.

        * Defect Id :   1-1A0Z0U
          Displaying process diagrams in the Editor is slow if the process
          contains one or more mapper tasks with a large number of mappings.
          This configuration also slowed down the debugger.  The performance
          problem was caused by code that iterated through the diagram
          several times, and was fixed by optimizing this loop.

        * Defect Id :   1-153QDV
          The current version control mechanism reviews each file in the
          repository before allowing a user to check in any changes.  This
          feature has been enhanced to allow the user to choose specific
          added or edited objects to check in.

        * Defect Id :   1-15UAGT
          Enhancement to have the signal out task publish explicit nulls.
          By setting the property
            "Config.Primary.Compatibility.SignalOut.publishExplicitNull"
          to true, the signal out task will be able to publish explicit nulls.
          The property is defaulted to false.

        * Defect Id :   1-15PBJS
          Enhancement to support multiple definitions of Transformation
          Plugin. The following properties need to be set:
          
              Config.Primary.messaging.Callouts.supportMultipleXforms: true
              Config.Primary.messaging.Callouts.&ltplugin name>: endpoint1,endpoint2,...

          Note that endpoint names do not include the full repository path
          names.

          For debugging purposes, set Config.Primary.messaging.Callouts.debug: true

          Also note that to use the transformation plugins, users now have to
          enable this feature explicitly by setting
              Config.Primary.messaging.Callouts.enableCallouts: true
              
        * Defect Id :   1-UYHLT
          Support the deployment of IM within the TIBCO Administrator 5.1.x framework.
          Please see readme.deploy for more details.

        * Defect Id :   1-1BU0SN
          There was a problem initializing the security component by the IM
          Designer GUI. This prevented testing HTTPS in the debugger. This is
          now fixed.

     Mapper, XML Parser and Renderer Issues:

        * Defect Id :   1-15R7RG
          If mapping to an AE schema, the mapped attribute does not publish
          out with the default value but the other non-mapped attributes do.
          This has been fixed.
          For AE default values to be used, the property
          "Config.Primary.Compatibility.AE.DefaultValues" must be set to true.

* Known Issues:

     Mapper, XML Parser and Renderer Issues:
        1) The following is a list of reserved words used by IM Mapper code. They
           should not be used to name XML elements and attributes:
               choice, sequence, CDATA, ANY, union, sequenceGroup, choiceGroup,
               sequenceGroup, choiceGroup, anonClass

        2) (Windows only) If a VFile repository exists immediately under &ltdrive>:/,
           IM Editor is unable to load the repository, throwing a Repo-Client error.
           This problem will be fixed with an up-coming IM 5.0.1 hotfix that includes
           a later version of TRA 5.x.
