If a ComponentProvider is registered, then Jersey will ask it for
every component it needs to instantiate (providers and resource
classes, Jersey specific or application-specific). If the component
provider returns null then Jersey will instantiate using it's own
component provider.
So i think the Guice ComponentProvider needs to be prepared to handle
such errors.
In this specific case you are seeing a Jersey-specific JAXB message
body readers/writers attempting to be instantiated. These are created
an servlet initialization time.

That does not look right, what happens when you try using curl?

A zip file and dependencies on all sorts of maven repos is fine as
long as i can run and debug it :-)
