Need to trap "com.ctc.wstx.exc.WstxUnexpectedCharException" in
ReadHeadersInterceptor and give HTML response message

Key: CXF-1490
URL: https://issues.apache.org/jira/browse/CXF-1490
Project: CXF
Issue Type: Improvement
Components: Core
Reporter: Glen Mazza
Priority: Minor
If an HTML response in returned from the service to the client, due to a basic
authentication or other error, the following error stack is returned (if
chunked transfer encoding is set to FALSE for the HTTPConduit/client*):
[java] Caused by: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected
character '"' (code 34) in DOCTYPE declaration; expected a space between public
and system identifiers

This requires the user to go to Wireshark[1] to determine what the HTML error
message is. I think it would be helpful for the user if this error was
trapped, and the HTML error message output to the client console as part of the
exception, to save that step.
Steps to duplicate: Make an HTTPS client connection to a server with (a) wrong
username and/or password and (b) chunked transfer encoding set to false as
shown here:
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:sec="http://cxf.apache.org/configuration/security";
xmlns:http="http://cxf.apache.org/transports/http/configuration";
xsi:schemaLocation="http://cxf.apache.org/configuration/security
http://cxf.apache.org/schemas/configuration/security.xsd
http://cxf.apache.org/transports/http/configuration
http://cxf.apache.org/schemas/configuration/http-conf.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd";>
<http:conduit
name="{https://myhost.com/this/is/namespace}MyPortName.http-conduit";>
<http:authorization>
<sec:UserName>???</sec:UserName>
<sec:Password>???</sec:Password>
</http:authorization>
<http:tlsClientParameters secureSocketProtocol="SSL"/>
<http-conf:client AllowChunking="false"/>
</http:conduit>
</beans>
Running the client should produce the above error stack.

* if chunked transfer encoding is true, we get a HttpRetryException error
message as shown here:
http://techpolesen.blogspot.com/2007/08/javanethttpretryexception-cannot-retry.html;
this is not currently a concern for me.
