Hi all, In general I see open source projects using abstract classes for extension points, as that provides for a migration path in the event of an API change, versus breaking any code that has implemented the interface.
I see some interfaces being used in Tika, e.g. Translator. Does the ServiceLoader require that these be interfaces? I assume not, as isAssignableFrom() should work with either interfaces or abstract classes, right? Asking because I'm looking at the language detector API for 2.x.
