My point exactly, nothing has been decided, perhaps it's time to make some decisions
Agreed.
I read this as build a better VM than HotSpot under the APL, *and* write the class libraries. I don't read this as take kaffe or JRVM or any other product and slap an Apache sticker and go faster stripes on it. The proposal seems to be clear about writing from scratch if it isn't then my bad.
That was my original impression as well. Besides, as a practical matter, rewriting an existing codebase doesn't necessarily save you time. It can do the opposite, in fact, depending on the state of the codebase. Maintaining somebody else's code is no picnic, and they might make assumptions in developing their own codebase that don't apply in your project.
So I suggest that, with regards to the VM at least, it should be our own cleanroom VM. Really, Harmony is three projects. First, we need a build environment. Second, we need a conforming VM. Third, we need a class library. I suspect three will be the biggest issue. The Java platform API is huge.
