Regression: Problem with new line for String param in client WS (JDK8 141 OK, JDK 161 ERROR)

[Tomas-Kraus]

There is a new regression based on the latest release of JDK.
I have reproduced the problem using non JDK version of JAX-WS (version 2.3.0:

	<dependency>
		<groupId>com.sun.xml.ws</groupId>
		<artifactId>rt</artifactId>
		<version>2.3.0</version>
	</dependency>

The problem visible only when using combination of client WS and SoapHandler.
It fails with message "Entity References are not allowed in SOAP documents" where the reference is "#xd" inside createEntityReference method call. It seems that new lines are now escaped (#xd or #0a).
And this seems to bug createEntityReference logic.

Example:

	// use any WSDL based service/port
	BindingProvider bp = (BindingProvider) service;
	Map<String, Object> ctx = bp.getRequestContext();

	List<Handler> handlerChain = bp.getBinding().getHandlerChain();
	handlerChain.add(new SOAPHandler<SOAPMessageContext>() {

		@Override
		public boolean handleMessage(SOAPMessageContext context) {
			SOAPMessage msg = context.getMessage(); // --> CRASH
			// do something with msg (like logging)
			return true;
		}

		@Override
		public boolean handleFault(SOAPMessageContext context) {
			return true;
		}

		@Override
		public void close(MessageContext context) {
		}

		@Override
		public Set<QName> getHeaders() {
			return null;
		}
		
	});
	bp.getBinding().setHandlerChain(handlerChain);

	// WORKS
	service.echo("AABB");
	// DOES NOT WORK
	service.echo("AAr\r\nBB");
