  * PROBLEM DESCRIPTION: DataObject.getList("booleanProperty").s *
  *                      et(4, Boolean.true) will increase       *
  *                      list size by 1                          *

  * RECOMMENDATION:                                              *
  ****************************************************************
  If the "booleanProperty" is a multi-valued property of SDO
  Boolean type, setting a new value to the list will increase
  the list size by 1 instead of replacing the indexed value with
  the new value. In other word, the list size should remain the
  same.
  

Problem conclusion

• This problem only occurs when the original list element is
  null. When it's replaced with a new value, the back-end XML
  data were not updated to remove the old value. Below is the
  code snippet to test this scenario.
  
  ArrayList booleans = new ArrayList();
  for (int i=0; i < 5; i++) {
  booleans.add(null);
  }
  dataObject.setList("boolean", booleans);
  assertTrue(dataObject.getList("boolean").size() == 5);
  dataObject.getList("boolean").set(4, Boolean.TRUE);
  assertTrue(dataObject.getList("boolean").size() == 5);
  
  APAR PM06281 is currently targeted for inclusion in Service
  Level (Fix Pack) 1.0.1.3 of WebSphere Application Server v7
  Feature Pack for Service Component Architecture (SCA) Refresh
  Pack. Please refer to the Recommended Updates page for
