  ****************************************************************
  The Web services CXF code in Liberty could not process an
  incoming SOAP message that was gzip encoded and failed with the
  following error:
  org.apache.cxf.binding.soap.SoapFault: Error reading
  XMLStreamReader.

Problem conclusion

• This problem occurred because the CXF code did not have the
  correct Gzip interceptor loaded to process the gzip encoded SOAP
  message. The problem was fixed by adding a custom JVM property:
  cxf.add.gzip.in.interceptor. If this JVM system property is set
  to true, CXF will load the correct Gzip interceptor for
  processing the gzip encoded SOAP message.
  
  The fix for this APAR is currently targeted for inclusion in fix
  pack 20.0.0.1.  Please refer to the Recommended Updates page for
  delivery information:

Temporary fix

• There is no workaround available for this problem.
