Thanks Sergey!
I have almost put it together at this point.
One thing that wasn't immediately clear is that the exception mapper is "a
provider"
and can be registered as follows (makes sense to add to the same wiki

<jaxrs:providers>
<ref bean="restCustomExceptionMapperProvider"/>
</jaxrs:providers>
Thanks,
