Thanks Gurkan.

I don't know that we have stuff that is deprecated pending removal at the
moment. In terms of removing the CMP/BMP stuff... well, people are using
it, which is why I'm working on it :-). I would be ok with marking it as
deprecated, as long as we print out an explicit warning if your application
is using it, so you know to migrate. In terms of the gain... I don't know.
There'd be less code, but I suspect still the same dependencies, so we'd be
removing a small part of openejb-core effectively. I think its a good
discussion, but I'd prefer to see graceful deprecation with clear warnings
before removal.

I'm sure adding comments to the code will be helpful, particularly for new
contributors - thank you.

We're currently on a CTR policy. It is perfectly ok to commit, and then
review. I personally prefer to commit stuff to my fork and discuss a diff
here before its merged. Even though I haven't had many replies on this
thread, just writing about what I'm running into helps. For folks that
aren't committers, the usual contribution methods are fine - GitHub PRs,
diffs attached to JIRAs, whatever works. The nice thing about PRs is that
your name is still attached to the commit when its merged, so you forever
get credit in the git log. Applying diffs from tickets works, and we'll
give credit of course, but the author in log will be whoever applies the
diff.

In other news, I think I have fix for my test. The bad news is that my Mac
chose that moment to blow fuses in 4 different chargers and needs to be
repaired, so I'm mid-swapping-over machines. I should get that pushed
tomorrow morning all being well.
