Yes, in version 1.2. That's why there's stdlib-jre7/8 and stdlib-jdk7/8 libraries.
@xenoterracide If you mean does it support publishing modules for jigsaw, I don't see any reason it can't. It just produces byte-code, so if you add the module files, it should 'just work'.
BUT I haven't tried it, nor have I seen any articles specifically on it.
