I'm thinking of doing a talk on Groovy for CinJUG. Any interest?

+1 Definitely!

Two comments:
(1) I think you meant "proprietary" rather than "commercial".
(2) As Jason pointed out, Jruby can be distributed under the LGPL which allows the proprietary portion of your code to be distributed source-less.


But on the topic of Groovy, I've been keeping my eye on it for a while.

It is very Ruby-like.  For example ...

 Groovy:  value = [1,2,3].inject('counting: ') { str, item | str + item
}
 Ruby:    value = [1,2,3].inject('counting: ') { |str, item| str +
item.to_s }

The big advantage to Groovy in an all-Java environment is that Groovy is

designed to use the Java libraries, where both (J)Ruby and (J|P)ython
come with their own system libraries.


There will be a session on Groovy by Christopher Judd at the Southern
Ohio Software Symposium (e.g. No Fluff, Just Stuff) this year (Aug 6-8).
