jdk not working in potato, working jdk removed from incoming, license problem

[jim@laney.edu]

Hi

I am given to understand that someone has found a problem in the license of
jdk, to the point that same person finds that debian cannot distribute the jdk
at all. I was told that the problem found in the license has existed for a
long time. 

If this is the case, 

WHY is a jdk that doesn't even work in potato? By precisely the same token, 
why is there a jdk in ANY debian dist?? Is there a difference in the license 
between versions? Has anyone talked to Sun?

If this is NOT the case,

Can this be resolved quickly please? I would imagine that it is the intent of
Sun that Java in its pure form would make it big. I have a few java projects
that I'm taking off the back burner presently, and now this.

Inquiring, jdk-using minds want to know.
