a hotspot-powered Javascript engine

[Sal]

Hi - I'm new to the list, if this is the wrong place to ask please forgive
me!

I recently have been reviewing the openjdk codebase, and have been thinking
to attempt a javascript-engine which is based on the openjdk.

The idea: to give the same performance to javascript, in a web browser that
of Java. (Or close to it.).  And create an engine that can be embedded into
the different browsers (Chrome, firefox, etc.)

My question: Is there any existing project(s) already doing this? I would
hate to reinvent the wheel.   If not, can any experts on the list give any
potential roadblocks/advice to help along the effort?

Thanks much in advance!

- Sal
