Hi,
When I upgraded the deployment of my Jersey application from JBOSS 4.2.3.GA (env:JDK5) to JBOSS 4.2.3.GA-jdk6 (env:JDK6), I met an error. The issue was in JAXBContextResolver, my class is:
@Provider
public class JAXBContextResolver implements ContextResolver<JAXBContext> {
public JAXBContextResolver() throws Exception {
this.m_context = new JSONJAXBContext(JSONConfiguration.natural().build(), m_types);
}
public JAXBContext getContext(Class<?> objectType) {
return (m_types[0].equals(objectType)) ? m_context : null;
}
private JAXBContext m_context;
private final Class[] m_types = {my.example.Representation.class};
}
1) I have configured my application.xml, including the providers;
2) I used different JDK env for different versions of JBoss.
Error message in JBoss console was:

I found the error occured in the line:
this.m_context = new JSONJAXBContext(...);
In the meanwhile, I made some tests,
1) No error when deploying my app in JBoss 4.2.3.GA (JDK5).
2) If I change the generic return type of getContext() to JSONJAXBContext, no error as well.
Does anyone have ideas?
