Hi James,
The Jersey JSON pom contains:
<dependency>
<groupId>com.sun.xml.bind</groupId>
<artifactId>jaxb-impl</artifactId>
<version>2.1.10</version>
</dependency>
You need version 2.1.10 to get "natural" support.
Annoyingly there is the usual issue of overriding the version of JAXB
in SE 6 for those using SE 6.
We need to do two things:
1) have better error reporting on what version of JAXB to use when
configuration natural; and
2) update the dependencies document.
Paul.
