[forge-dev] Regarding Errai and JBoss Plugin

Hi Luca, my comments are inline.

It sounds like you need to get in touch with the authors of these plugins
and see if you can get some enhancements made (or submit some pull requests
with enhancements yourself.)

As far as your presentation goes, I would just try to figure out what is
and is not ready to be shown. It seems like you have identified a number of
things that might cause problems during your talk, so you might want to
decide if you feel comfortable presenting them or not. If you think you can
improve and solve these issues before your presentation, that is another
option :) It's up to you. There is no good or bad path for a presentation;
there is only what you feel will be good or not, and what you want to show

Try the Errai plugin again BTW. I just merged a long-standing pull request
that incremented a bunch of versions and fixed a few things.

See below...

Sounds like this will need to be improved. You could submit a pull request
with your enhancements, or with with the developer to get it fixed,
depending on your time-frame.

Pull request? Contact developer.

Pull request? Contact developer.

How did you install JAX-RS? I'm not sure what you used to do this, so I
can't really comment, but if it's the errai-plugin, then I'm guessing it
would need to be patched.

Pull request and let me know when it's ready :)

Sounds like the Forge Eclipse integration needs a bit of work to allow
passing JVM args for memory. I've put an issue in for this:
