Karl,

Thank you for informing me of this Eclipse working group.  I wasn't 
aware of it.  And reading the page you mentioned was very very very 
hauntingly like the issues that led us to creating the DLJ license and 
the jdk-distros project.

The jdk-distros project is meant to be a staging ground for some of the 
linux-specific bits and documentation.  However it's focused entirely on 
installers, and not the JDK code itself.  The jdk-distros project uses 
the BSD license to facilitate even more fluid code sharing.

You are probably talking about source changes, not installer changes..?

The current contribution process is a work in progress and we know it's 
not the final one.  We plan to develop a better contribution process 
over time.  The process that's there is very similar to the process we 
use in-house that Sun engineers go through on every change we make to 
Java SE.  We take stability as a very high attribute and the process we 
follow involves a lot of peer review and unit/etc testing before it is 
allowed into the central source repository.

But, that said, any future contribution process is open for discussion.  
The appropriate place to take that is the mailing lists and/or forums on 
java.net.

We are open to, in the future, having external contributors with direct 
putback rights.  And that, too, is a topic for discussion.

BTW, one goal for the jdk-distros project was for it to hold the 
installer scripts for each distribution using the DLJ.  The 
Debian/Ubuntu scripts are in the jdk-distros repository.  The Gentoo 
scripts could be, if you desire, if there is any need for it. 

The purpose was along the lines of what you have discussed.  To 
facilitate sharing between the distribution makers of the installation 
procedures.

- David Herron
