  * RECOMMENDATION:                                              *
  ****************************************************************
  The pointers to the preceding and following nodes of an element
  with Native_Data state are lost before linking them together.
  This results in old siblings still referring to this moved
  node. This causes corruption and causes
  ArrayIndexOutOfBoundsException when trying to access the old
  parent's fast access array with the new index within new
  parent.
  

Problem conclusion

• Preceding and following nodes are linked before pointers to
  them are lost. This prevented data corruption and
  ArrayIndexOutOfBoundsException.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.4.  Please refer to the Recommended Updates
