Global custom exception handler in resteasy

Question

Is it possible to make global exception handler for all unexpected errors. Because it's impossible to make all possible classes like this:

public class ExceptionHandler implements ExceptionMapper<JsonMappingException> {...}

I want something like this:

public class ExceptionHandler implements ExceptionMapper<Exception>

You could probably do the following:

@Provider
public class GlobalExceptionHandler implements ExceptionMapper<Exception> {
    public Response toResponse(Exception exception) {
        return Response.status(Status.INTERNAL_SERVER_ERROR)
            .entity("An error occured").type(MediaType.TEXT_PLAIN)
            .build();
    }
}

I have just tested it in RESTEasy 3.0.6.Final and it seems to work. Keep in mind that the 500 Internal Server Error status code may not always be appropriate.
