RE: [beanutils][collections] Transformer, Predicate, and Closure Implementation
Thanks to you Robert for taking the time to look over my submission and
taking the time to incorporate it!
Forgive the stupid newbie question but... I would like to become more
active in the Commons, Struts, or Maven projects but am not sure where
to start. I've read the 'Get Involved' section and scanned the Apache
Bug Database and JIRA (for Maven) but I'm not sure where my help is
needed most and I don't want to step on toes by working issues that
other people are working.
Any suggestions would be appreciated.

hi norm
committed. many thanks.
i've added some documentation into the beanutils package.html (which is
where the main beanutils documentation lives). feel free to expand and
enhance it if you wish :)

You seem to have an interest in [collections], so perhaps you would fancy
looking at the Bugzilla. I am trying to pull strands together for a release,
so any javadoc checking, extra tests, or new classes from bugzilla would be
great.
If you find something, I suggest talking to the mailing list to check
current views. Don't forget to prefix with [collections] ;-)

hi norm
this is not really a stupid newbie question. the apache answer is find an
itch and patch it! this is easy to say but less easy to practice.
apache is more decentralized than many other open source organization so
you might need more patience and be more willing to take the initiative.
one description that's often repeated is that it's a do-ocracy rather than
a dem-ocracy.
what i usually do (where i'm not a committer) is find something i want to
do and then post a 'hey - anyone mind if i do this?' to avoid stepping on
anyone's toes.
if you're interested in maven then a lot of the developers hand around on
irc so that's a good place to hang around to find out the latest news and
who's working on what. if you've got a particular maven itch then that's a
good place to ask.
i don't think that there is a component in commons that has enough
developers.
if you're interested in the commons then you'll find that different
components are quite different - even if developed by the same people.
beanutils is very widely used and very mature. there is a very big list of
enhancements and patches but it takes a long time to review them since the
consequences of introduced bugs is pretty serious.
at the other end of the spectrum are commons-resources≤ commons-reflect
and commons-math. these are new and need a lot of work. it's easier to
commit patches for these and the impact a new developer could have on
these components would be bigger than for others.
in the middle are components like collections and lang. these are still
growing pretty quickly but they are widely used and so changes to the core
are likely to be reviewed very carefully.
hope this helps and i'd like to encourage you to get involved.
