Local fix

Problem summary

• When the class specified in the javax.management.builder.initial
  system property cannot be found, the JMX MBean server fails to
  start. Before Java 8.0.5.0, and in other Java implementations,
  when the javax.management.builder.initial class is not found,
  then a javax.management.JMRuntimeException is thrown, which can
  be caught and handled gracefully. The issue fixed here is that
  after Java 8.0.5.0, the IBM SDK for Java throws an
  ExceptionInInitializerError, which is not handled in the same
  way, causing an application error.
  

Problem conclusion

• The Java SDK has been updated to throw an exception that can be
  handled as before, rather than an ExceptionInInitializerError.
  .
  This APAR will be fixed in the following Java Releases:
     8    SR5 FP41  (8.0.5.41)
  .
