That's indeed a very difficult question. And there is probably nothing 
measurable. I argued with the silent user base still using Java 1.4 - 
they will probably also not stand up and shout "Now we us Java 5, you 
can switch."

But I trust in our community health. Just have a look around on 
comparable frameworks and see what they are doing. I mentioned Spring. 
Geronimo is another case: Still a J2EE 1.4 server they think about JEE 5 
- and so Java 5. But they also think about Java 1.4 compatibility, be it 
via retro* or via plugins. Unfortunately they came not really into 
discussion about this topic [1], but went on to JPA.

Another question is about the efforts according to the libraries we are 
using. At the moment I don't know any actually requiring Java 5. And a 
framework should IMHO definitely not walk in the first line.

So, no, I don't have anything measurable. And we will probably have to 
think about this topic again, be it in one year or with the next minor 
or major version of Cocoon.
