JAXBContext having defaultNamespaceRemap after release 4.0.3 produces unexpected xml

[cachescrubber]

The upgrade to jaxb-runtime-4.0.3 introduced an incompatibility when the defaultNamespaceRemap property is used.

I have an executable example project here on GitHub to demonstrate the issue.

Until 4.0.2 the produced xml was using a namespace prefix:

<ns2:helloRequest xmlns:ns2=\"http://demo.ws.example.com\"><name>Klaus</name></ns2:helloRequest>

After the 4.0.3 upgrade the produced xml is as follows:

<helloRequest xmlns="http://demo.ws.example.com"><name>Klaus</name></helloRequest>

Caused by #1715.

The Web Service having the issue was using Apache CXF as a client talking to Spring Web Services on the server side.
