Yes, that's exactly on the money.  For bean services, it creates a
subclass of the actual class to use as the proxy, and overrides all of
its public instance methods. Doing this requires a no-args

You might also find that having interceptors on the service will also
require a no-args constructor (even with the primitive service
lifecycle model, having interceptors requires a proxy or two in the
calling sequence).
