It must be somewhere in the JAXBElementProvider. Can you please try and register a custom JAXBElementProvider with the JAXRSServerFactoryBean ? This provider will only extend writeTo/ReadFrom and will have a try/catch block around super.writeFrom and readFrom ? I'll check the JAXBElementProvider, I think it has few catches for different types of exceptions including the Exception class - and in this case it should indeed print a stacktrace...Letting users to configure the default WebApplicationExceptionMapper for it to print the stacktraces is another option...
