APAR status

• Closed as program error.

Error description

• During WebSphere Application Server migrations, various XML
  documents maybe getting updated with default attributes and
  tags that didn't exist in the source configuration.  These
  default attributes and tags can cause changes in behavior.
  Specifically, classloader and mode="PARENT_FIRST" elements
  have been known to be added, which in turn have caused various
  classloading problems at server and application runtime.

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of IBM WebSphere Application      *
  *                  Server V8.0 migration.                      *
  ****************************************************************
  * PROBLEM DESCRIPTION: Default attributes are being            *
  *                      incorrectly added to XML configuration  *
  *                      documents during WebSphere              *
  *                      Application Server migrations.          *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  After performing a WebSphere Application Server migration
  there could be a change in the behavior of applications.  This
  is due to default attributes being added into XML
  configuration documents.  Most reported incidents have
  involved class loading issues where there has been a change
  from parent last to parent first class loading.
  

Problem conclusion

• The WebSphere Application Server migration code now checks to
  see if default XML attributes were a part of the old WebSphere
  Application Server configuration documents before adding them
  to the new WebSphere Application Server configuration documents.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.4.  Please refer to the Recommended Updates
