Custom ErrorDecoder wraps Exception in java.lang.reflect.UndeclaredThrowableException #386

//...
.errorDecoder(new ErrorDecoder() {
                    @Override
                    public Exception decode(String methodKey, Response response) {
                        if (response.status() == 404) {
                            return new NotFoundException("product not found");
                        return errorStatus(methodKey, response);
//...
try {
   apiProxy.getStuff();
} catch(Throwable t) {
//t is java.lang.reflect.UndeclaredThrowableException, but should be NotFoundException
Is this really the desired behaviour? I expected to see my own exception-class thrown at this point.
