  ****************************************************************
  The getParameterableHeaders() method tries to parse non-system
  headers as Address headers, even if they are not so. This causes
  a parsing exception to be thrown
  

Problem conclusion

• We now verify whether the header is an Address and if not,
  parse it as a simple parameterable header.
  The fix for this APAR is currently targeted for inclusion in
  fix pack 1.0.0.11. Please refer to the Recommended Updates page
