  sourceHandlerWrapper.java:47)
  

Problem conclusion

• The code has been updated to handle empty strings and throw an
  NPE if the resource is null, per the JSF specifications.  The
  open source issues are MYFACES-4065 and MYFACES-4187,
  respectively.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.5.10 and Liberty version 21.0.0.8.
