Yesterday's proposal (scroll down to Proposal for an Apache J2EE server project) causes lots of talk on the email@example.com list. From "I want to be in it, pliiiize!" to "how about you guys eat JBoss while you're at it", but in any case this seems to be a hot subject.
I'm not much familiar with the JBoss community but several people seem to be disappointed by it. Hey, not all communities can be as healthy as Cocoon ;-)
