WebSphere MQ V7.0 Fix Pack 7.0.1.4
WebSphere MQ V7.0.1 for i5/OS Fix Pack 7.0.1.4

APAR status

• Closed as program error.

Error description

• When using a registered exception listener for an XMS .NET
  client application, the Exception Handler throws an
  InvalidCastException. The following is an example of
  such an exception:
  
  14:56:37.292812  1712.0004  IBM.XMS.WMQ.WmqConnection
  -  d  DeliverException(): Exception Handler threw exception :
  System.
  InvalidCastException: Unable to cast object of type 'IBM.XMS.
  IllegalStateException' to type 'IBM.XMS.Provider.
  ProviderExceptionListener'.
  at IBM.XMS.WMQ.WmqConnection.DeliverException(Exception e)
  
  This occurs when the registered exception listener encounters
  an exception thrown by a call in the XMS .NET application.
  

Local fix

Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of XMS .NET applications that use an Exception Listener
  when connecting to a WebSphere MQ v6 queue manager.
  
  Platforms affected:
  Windows
  
  ****************************************************************
  PROBLEM SUMMARY:
  There was an error in the way XMS .NET client invoked the
  Exception Listener when connected to a WebSphere MQ v6 queue
  manager. Instead of invoking the registered exception handler
  with the exception object, XMS .NET incorrectly assigned the
  exception object to the Exception Listener variable causing an
  InvalidCastException to be thrown.
  

Problem conclusion

• XMS .NET client has now been changed such that the registered
  Exception Listener is invoked with the exception object when
  connected to both WebSphere MQ v6 and v7 queue managers.
