Technically incorrect... Dalvik is a VM, and the implementation of it, according to Oracle's claim, is infringing on Sun's patents.

Note that Dalvik is essentially just an alternate stack-based virtual machine for bytecode that's been converted from the standard stack-based JVM bytecode. You still need a standard Java SDK to develop Android applications in order to compile the Java source code to JVM bytecode. So far Google has been able to get the best of both worlds by leveraging the vast Java tools ecosystem but then in the final step they convert the standard JVM bytecode to run on their own Dalvik VM which means they don't have to pay license fees for the standard Java runtime. IMO this is what is really annoying Oracle. (To be fair there are also good technical reasons why they created Dalvik.) I can understand where Oracle is coming from legally, but business-wise I think this lawsuit is bound to backfire. Google has the resources to defend themselves and move away from Java in the long term, but in the meantime Oracle has created serious uncertainty about the openness of the Java platform which will scare technically innovative players away from Java that don't have the financial and legal resources that Google does. So Oracle turns Java into the new COBOL, a technically moribund backwater that is only kept alive for legacy purposes.

  I don't know why Dalvik exists. The JVM is GPL'd, you don't have to pay license fees to use. There are other Apache licensed JVM's (http://harmony.apache.org/ http://harmony.apache.org/). If this lawsuit drives people towards the Newspeak and V8 VM that would be a good thing.

I sincerely hope that this lawsuit results in dalvik being removed from android. They should never have used dalvik. It's an arm linux. They should have stuck to gcc toolchain like every other arm linux implementation out there. They are missing out on a wealth of development resources for no reason at all.
