this is exactly the point. And this might also be (one of) the reason(s) why Google PR is calling the suit against them a suit against Open Source in itself.The other conclusion would be that Sun, and now Oracle, are schizophrenic hypocrites: let's not blame it solely on software patents.
I believe the GCJ is vulnerable because, like Dalvik, it's not derived from the OpenJDK.
Well, not being VM based it should be free of some or all of the patents used by Oracle in that part of its lawsuit against Dalvik, but that doesn't mean that it wouldn't be otherwise vulnerable.
The right conclusion to make seems to be that software patents are bad.
