  Additionally, it is possible for Liberty users of JSF-2.0 to
  be affected if the view state string is modified improperly in
  any way.
  

Problem conclusion

• The JSF implementation was updated to handle a missing or
  corrupt viewstate string to avoid this NPE. The fix for this
  APAR is currently targeted for inclusion in fix packs 8.5.5.20
  and 21.0.0.6.
  
  Note: IBM WebSphere Application Server
  version 9.0 is unaffected by this NPE.
