    <featureManager>
      ...

Problem conclusion

  • The problem was caused by specified incorrect package name in
    the code. It has been corrected.
    
    The fix for this APAR is currently targeted for inclusion in fix
    pack 17.0.0.4.  Please refer to the Recommended Updates page for
    delivery information:
    http://www.ibm.com/support/docview.wss?rs=180&uid=swg27004980
    

Temporary fix

  • The monitor-1.0 feature should work fine but only the Perf MBean
    will not be available. If do not want the ffdc be generated, do
    not set the enableTraditionalPMI to true.
