Which jdk (spec. javac) does DDE use?

I’ve been developing Notes apps for 15 years, and in the last few years I’ve been slowly but steadily building up steam on the Java side of things.

One very specific question in this post : where is javac ?

I have this Win7 machine, with a Notes client, Domino Admin, Designer and Server and no other Java development environment whatsoever. (I don’t do “pure Java” often, but when I do it’s in Linux.)

I’ve been rumaging a bit both through my file system and the internets, and I still wonder : which JDK does Domino Designer on Eclipse use ? Is there some sort of javac equivalent somewhere ?
