A "JVM" is not a Java language interpreter anyway but a Java byte code interpreter. AFAIK all those other languages only run on Dalvik by first being compiled to Java byte code format, thus it is arguable that they are all "Java" as far as the VM goes.
What Google needs is something that compiles directly to Dalvik's own native format which has no "Java" at all in the pipeline.
You seem to think the JVM bytecode format is specific to the Java Programming Language™; why is this?
Admittedly Sun has muddled things up here by using the word "Java" to mean many separate things.
1) impolite. 2) your comments should concentrate on what you can add to the convo, not what others haven't.
I mean, it also doesn't help that your statement was incorrect (P-system as mentioned), but being rude in what is ideally a civil forum dedicated to a stated purpose is not helpful.
Reading comprehension, bro. Give it a try.
The Dalvik VM, like the Java Virtual Machine, is quite capable of running languages that aren't Java. There's nothing controversial or incorrect about that statement.
This is already pretty clear; you can run Lua, Scala, Javascript, Scheme, Ruby, and many other languages on Dalvik.
