PH45221: NPE IN COM.IBM.WS.ZOS.WLM.INTERNAL.UNAUTHORIZEDWLMNATIVESERVICES.CREATEJOINWORKUNIT()

APAR status

• Closed as program error.

Error description

• When the com.ibm.ws.zos.core.angelRequiredServices property
  is
  set in the bootstrap.properties file and includes SAFCRED in
  the
  list without also including ZOSWLM, users may see a
  NullPointerException like the following:
  
  [com.ibm.ws.jca.internal.BootstrapContextImpl(641)] : The
  activate method has thrown an exception
  java.lang.NullPointerException

Local fix

• Include the ZOSWLM option in the
  com.ibm.ws.zos.core.angelRequiredServices property, e.g.:
  
  com.ibm.ws.zos.core.angelRequiredServices=SAFCRED,ZOSWLM

  A NPE can occur when using the Unauthorized native WLM services
  without the proper Security setup.
  The required setup is to have READ permission in the
  BPX.WLMSERVER profile under the FACITITY class.
  Without the appropriate permission the native connect call to
  WLM returns a failure to the invoking JAVA
  code.  The design for the handling of this failure was to build
  and throw a SecurityException from the
  activate() method where the WLM connect was driven.  This would
  disable the UnauthorizedWLMNativeServices
  OSGi Service and prevent future calls to it.   The returned
  information from the native WLM connection failure
  was not properly handled and resulted in the OSGi Service for
  UnauthorizedWLMNativeServices to be instantiated and
  used.
  

Problem conclusion

• Code has been modified under the
  UnauthorizedWLMNativeServices.activate() method to properly
  handle a failed
  native WLM Connect and cause the OSGi Service for
  UnauthorizedWLMNativeServices to not be instantiated.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 22.0.0.5.  Please refer to the Recommended Updates page for
