Local fix

• WTXCQ - WTX00039184
  PVB / PVB
  Circumvention: None
  

Problem summary

• Users Affected:
  WebSphere Message Broker 7.0.0.3 users of the WTX Transformation
  Extender  Plugin Node are affected when the Broker is using
  JRE1.6 SR9 FP1.  When using JRE1.6 SR9 FP2, the problem does not
  occur.
  Problem Description:
  The Message Broker Plugin node causes a crash whenever the JVM
  is not initialized or reported as being initialized by the JNI
  layer.
  Platforms Affected:
  ALL
  

Problem conclusion

• The WTX Node detects JVM/JNI initialization failures and avoids
  crashing as a result.  Any JVM/JNI initialization failures are
  logged to the Service trace and an error code is propagated back
  to the Broker environment layer. JRE has to be updated to
  correct this error condition.
  Delivered in:
  8.3.0.5, 8.4.0.1
