If you hadn't heard Oracle has sued Google over the Dalvik. Dalvik is a knock off of JAVA. It's a clean room implementation but apparently there are some patents that Oracle is alleging that Google is infringing in addition to some other charges.
Since Bilski didn't clear up the patent mess it looks Google is going to have fight a pitched battle with Oracle. If Google rolls over and just pays off Oracle, it won't bode well for FOSS applications that rely on JAVA.
The irony in this situation is that everyone complained about Mono and the submarine patents that MS could potentially wield against any free implementations. Instead, we've now discovered that our new JAVA overlords aren't as friendly as Sun. It's not really surprising. Gates, Jobs, Ellison have the same basic business personalities. It's now holds barred and anything goes. Oracle is shooting itself in the foot just like MS and Apple has.
I wonder how much Oracle will start charging for either the JAVA runtime, SDK, or both. Oracle will probably squeeze as much money out of JAVA as they can. They bought it after all. It just seems sad that the nice ecosystem that has grown up around JAVA could be in trouble now.
Watch Patent Absurdity if you can.
Groklaw has a nice write up of the situation.
