Gang, JetBrains used to, and probably still do, provide Ultimate Edition to Apache committers. I personally don't use that anymore, as the "full suite of apps" are now (to me) reasonably priced compared to a few years ago.
I think opensou...@jetbrains.com should be used to request. State that it is for Apache Software Foundation, and the Apache Zest project with link to http://zest.apache.org Cheers -- Niclas Hedhman, Software Developer http://zest.apache.org - New Energy for Java
