This sound great. One idea for this is inviting Stuart Ballard (CCed).
His japitools have been a great part
of the communities conformance and compatibility drive.

Does it have to be a separate group? Couldn't this be part of the
quality group? They already have a (pretty quiet) mailinglist and
infrastructure on the website. It seems conformance is just one bit of
the quality process overall.

I do have my doubts about this second part though. Is it really in the
interest of the openjdk project to have secret lists where proprietary
software is discussed without the rest of the community being able to

free software community, where all software and ideas are shared in the
open. There are still of course the binary blobs and the jtreg suite,
but my understanding is that those will be liberated over time (as
icedtea and mauve have shown can already be done). Is the idea that over
time the JCK will also become a proper part of OpenJDK under a free
