There is no time line, we have discussed it a bit. We might bring it up
at our next meeting.

There is not

Thanks for submitting these patches. I assume they are just ebuild
patches because if it's more than that. Submissions of patches would
surely be useful.

Great, where's the patch for Eclipse? Since it REQUIRES 1.4 to be
present to be built. At least that was the last state of the sources
from upstream.

Might want to look to see if stabilization requests have been filed. Or
if the gen 2 versions have been in tree long enough to be stabilized.
Because your requesting what has been done already, and there is a
process to migrating packages.

Tomcat is one of our best maintained Java apps, if I can toot my own
horn for a bit. Also FYI, your rush to 1.5 causes problems. For example
that patch you provided dropping deps for Tomcat 5.5.x when using 1.5,
via java5 USE flag. Caused several bugs to pop up, a few deps were over
aggressively dropped and I added them back. There is still one remaining
problem with catalina.jar and the manager app when deploying,
restarting, and undeploying an app. A user wasted considerable time
tracking that down.

So we are not looking to introduce breakage, bugs, or problems like that
to our stable tree. By rushing to get everything compiling with, and
using 1.5. Although it is a goal. Others teams might feel that is
acceptable, but we on the Java team and with our Java herd of packages
have pretty high QA standards.

Thank you for your input. We have been desperately working on this.
Schedule meetings so we can all stay focused, goal oriented, and be
working as a team. However some of us (like me) have lost considerable
time due to breakage else where in the tree. If time was not lost like
that, then we might be further along.

We have been recruiting for some time, and bringing on new people as
fast as we can reasonably. But we are all volunteers, and can only do as
much as we can in our free time. If you are unhappy with the state of
things, I would suggest helping out in the process. Also doing a bit of
home work on said packages or the state of things. Before commenting in
a negative manner towards those busting there rears to maintain 400+
java applications in the Java herd alone. Much less in other parts of
the tree.

Math alone breaks down to like ~40 packages per dev, and with my efforts
on Tomcat and etc. I have little time for gen 2 migration or maintenance
of other packages. All the while trying to increase our package
offerings by packaging stuff like glassfish. Much less virtuals so users
can choose implementations of things like jaf, javamail, jmx,
servlet-api, and etc.
