It's no secret that various governmental agencies around the world are looking at Oracle's Sun acquisition, specifically from the perspective of Java.
I have a lot to say about this, but I'll start with one comment....
In order to demonstrate that there would be reasonable choice and competition in the ecosystem should the acquisition be approved, the obvious thing for Sun or Oracle to do is to just give the Apache Software Foundation a reasonable license for the Java SE TCK so that the Harmony project can certify our implementation as compatible with the spec.
Java would then arguably be an open ecosystem with users having choice in implementations for the JRE and JDK.
IANAL, but it strikes me that at that point, the various anti-trust watchdogs would have a lot less to talk about, and we can put this whole pathetic chapter behind us.
