Technically, switching to new Java version is not that hard, things that you need to do are:
1. Change required Java version in our parent pom.
2. Change profile in Continuum so it uses Java 1.5
3. Upgrade Java used on
4ยท Announce this fact to our users.

In the past, it proven to be more social issue that some people were blocking decision about

changing required Java version. At this moment, I don't see any kind of that effect (it looks
every one agrees on the need of change) so I don't think we need to exploit this situation
switching to Java 1.6 immediately.

I agree with Peter's arguments that there should be no hurry. On the other hand, I agree with
that we'll need to switch to 1.6 in a year but provided there are no people blocking this
and we have more frequent releases of Cocoon Core I prefer gradual steps.

If there is anyone who wants to add something to this discussion I think it's a perfect time
speak out now. Otherwise, I would like to call a vote next week so we can make a formal decision.
