Problem summary

• ****************************************************************
  USERS AFFECTED:
  Users of the MQ classes for Java/JMS with the MQ Trace enabled.
  
  
  Platforms affected:
  MultiPlatform
  
  ****************************************************************
  PROBLEM DESCRIPTION:
  Having a MQ Classes for Java/JMS application with trace enabled
  and running embedded in Oracle database will fail on the attempt
  to obtain the JVM Process ID via a call to
  "ManagementFactory.getRuntimeMXBean().getName()".  The value
  returned by this call is not in the expected format and when it
  is attempt to be converted to a integer value results in a
  java.lang.NumberFormatException.  This is due to the method call
  return a string having the following content
  "(PID=57324;SID=1185)@hostname", rather than the expected value
  "57324@hostname".
