J source is available under GPL, but historically earlier versions have been available under other, simpler licenses.
Note also that the GPL's self propagating aspect only applies if you propagate the GPL'd code. Finally, note that copyright needs to be taken with a few grains of salt. Each creative community has its own traditions for what kind of copying is "acceptable" and "unacceptable". Mostly the rules boil down to: be fair and avoid litigious situations. And, in fact, courts tend to follow this practice also - first looking for people to make reasonable compromises before getting into the time consuming (and expensive) process of going through the facts behind each party's arguments about what's going on. Anyways, J is available under several licenses, so your "do they share J's license" question isn't really well-formed. But it's extremely unlikely that any reasonable use of JDB is going to land you in court. And the same applies to the rest of JAL. I think we all have better things to do with our time.
