Swing can be used in 1.1 also.

Collections can be used in 1.1 also.

The problem could be worked around.

There is only one place where we can't have 1.1: MemoryStore. I love the
idea of weak references and I'm sure that we can get around some
implementation limitations by fragmenting the memory... anyway, yeah,
cocoon 2.0 could work on 1.1 just as it works on it right now... but we
_must_ push this a little forward.

Ok, this all comes down to the real issue: performance.

I _KNOW_ that IBM JDK 1.2 for both win32 and linux (codename Colorado)
is ready to ship and faster than 1.1.8 on both platforms.

So, do you seriously believe that by October they would not release it?

Well, if that doesn't happen and IBM has serious issues with Sun, having
Cocoon tied to 1.2 is going to be the least of your troubles :)

                          able to give birth to a dancing star.
