Local fix

• WTXCQ - WTX00038300
  GK / GK
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Transformation Extender JMS adapter users
  
  Problem Description:
  An error occurs when using more than 1 WTX JMS connection when
  running under an Apache ActiveMQ JMS provider.
  
  Platforms Affected:
  ALL
  

Problem conclusion

• Each JMS connection is given a unique id.  This ensures that a
  JMS provider does not raise an exception when it detects WTX
  opening multiple queue sessions that are assigned non-unique
  client IDs, as is the case with Apache's ActiveMQ JMS provider.
