Are there any other licenses used in the OpenJDK code base besides the ones you've already described?

Yes. The demo and sample code modules are released under the BSD license. These code elements are intended to be very widely distributed, freely modified and used.

Accordingly, we've chosen the BSD license as most appropriate for these uses. Because these components are not part of the JDK but rather are application programs, they need not be under the GPL license because of the Classpath exception. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
