  If you create a sequenced data object, make a copy, then add a
  value to the copied sequenced data object, it will result in
  a NullPointerException. Below is one example.
  
  DataObject dobj = dataFactory.create("mynamespace",
  "SequencedType");
  dobj = copyHelper.copy(dobj);
  dobj.getSequence().add("myProperty", "test"); // Throw NPE
  

Problem conclusion

• The root cause of this problem is the Cursor/element
  representing the sequenced data object was released
  prematurely. The solution is to keep the reference until not
  needed.
  
  APAR PM19038 is currently targeted for inclusion in Service
  Level (Fix Pack) 1.0.1.7 of WebSphere Application Server v7
  Feature Pack for Service Component Architecture (SCA) Refresh
  Pack. Please refer to the Recommended Updates page for
