JDK-8172297 caused issues with ApacheCXF JAX-WS deployements. The fix makes use of the XMLStreamWriter.writeEntityRef method, while this is not allowed when using SOAP based web services.
StackTrace :
    Caused by: java.lang.UnsupportedOperationException: Entity References are not
    allowed in SOAP documents
