SUN Java and OpnJDK has always shared almost all cod. And Oracle has
announced that they want to make OpenJDK the RI. So it seems fair to
assume that for 7 the code is flowing OpenJDK->Oracle Java.

But some Java's may still be better than others. More users =>
easier to get help with installation, better performance, faster
bug fixing etc..
