Sorry for being pedantic, but I think it would be ideal if we wrote the entire implementation ourselves. EPL ist still not as permissive as MIT.

Inheriting the Sun launcher is fine (it wouldn't introduce a new dependency) as long as we write the overridden methods completely ourselves and possibly call super where needed.

I think your advice is indeed and acceptable. I'll have a try :)
I'll open a new pullreq when it is ready!
