****************************************************************
During materializing of a copied node, a notification was
being sent to the copied of the node to unnecessarily
materialize themselves. This extra operation was causing data
corruption in the copied nodes. This can cause an
ArrayIndexOutOfBoundsException in the
FastAccessMediator.getInternalFastAccess method.

Problem conclusion

  • The materializing algorithm got updated to avoid materializing
nodes (elements, attributes and namespaces) when it is not
needed by disabling the mechanism for sending notification to
the copied node during materializing.

The fix for this APAR is currently targeted for inclusion in
