Could you clarify what kind of patents (or what patents) are the problem with OpenJDK, with its GPL+linking license?
We are free to link anything in JDK with our application and use whatever license we want when selling, giving or distributing it, or aren't we?

I wouldn't be surprised though to know there are many problems.
The whole US software patent system is f*d up anyhow, whatever is done it smashes against some patent(s) and only big companies can afford to defend patents. I would say whole US legal system is a joke with all those extra blood sucking lawyers and TV commercials.

I know, Java for "mobile devices" have issues. Namely mobile phones are not included in "general purpose computers" which the license talks about.
But they need to change that, or .NET or Dalvik takes over. If Google looses its legal fight to Oracle, then .NET, and would think IBM and Oracle would not want it to go that way.
Or....fork Python to be statically typed and fast by making intelligent JIT with adaptive optimizations.
