It depends what you mean by “expose”. You can register an object as a service, yes, but if it’s not implementing an interface, what kind of service will it be? You can only register it as its own type or as java.lang.Object. This is not very useful except in rare edge-cases.
If you publish it as its own type and clients look it up by that type, then the clients are not decoupled from the implementation and you defeat the whole purpose of using a service. If you publish as java.lang.Object then how to clients know what methods they can call? They would have to use reflection; the Gogo shell works like this but it’s very unusual.

REMARK : This class does not implement at all an interface. Regards, -- Charles Moulliard Apache Committer / Architect @RedHat Twitter : @cmoulliard | Blog : http://cmoulliard.github.io
