  This exception occurs because the JSF 2.0 code attempts to
  load a servlet class that has already been destroyed.  This
  exception causes no functional problems, and can be safely
  ignored.

  a servlet class that has already been destroyed.  The exception
  causes no functional problems, and can be safely ignored
  

Problem conclusion

• The Liberty JSF 2.0 code was updated to avoid attempting to load
  classes which have already been destroyed.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 19.0.0.1.  Please refer to the Recommended Updates page for
