Proposing projects for OpenJDK

Hi Martijn, all,

(speaking as the author of JITWatch) definitely +1 for waiting until it's
in a stable state.

I've got a few more features in my head that I think are quite important
for a usable v1. I also need to increase unit test coverage and try it
across a good sample of hotspot logs. I tried with a 200MB log from
Eclipse and ran into PermGen problems so want to make sure it scales as a
tool.

As a request, I'd be grateful to receive any hotspot -XX:+LogCompilation
logs people are willing to share (core classes or common libs preferred as
classes need to be available, no need for source). Email to
chris at chrisnewland.com thanks :)

Kind regards,

Chris
