Re: Contributing The SableVM Virtual Machine To The Harmony Project

Hi,
     This is a great move.

I would like to underline an additional important project being added to=20
the Apache project: Oscar OSGI.

Oscar OSGi already runs on the 770. OSGi has become a JCP.

Knopflerfish refused Apache's offer for an obvious reason: we target=20
embedded.

So, will SableVM care about a modularity that will continue to support=20
the recent great refactoring? Will it care to maintain Classpath=20
compatibility?

If so, we at Gatespace Telematics will be more than happy to gradually=20
dedicate more and more resources to various improvements around and in=20
it. I'm thinking mainly of the JIT.

We have 4 compiler engineers on staff. Most of them are lost in the=20
functional languages world of Erlang :-), but we have two guys who know=20
a whole lot about embedded Java.

We hope you share our enthusiam in taking SableVM to the next level. We=20
believe it can make it. SableVM is the most complete free JVM project to=20
date, who would contradict that?

Best Regards,
