Hi Norbert,

your concern is right, as far as IBM consider that WebSphere 5.x is 
still a live product. By the end of this year, WebSphere 5.x will be 
dead and all IBM users will be ask to switch to WebSphere 6.x, if they 
want to be supported.

I know that customer with working applications may perfectly continue to 
run them on non maintained versions of WS, but we still have a 1.0 
version which will be perfect for that. btw, WebSphere 4.0 is using a 
1.3 version JDK, and we still have people around the world using WS4 
(trust me : I'm a living witness :)

So having a 1.0/jdk 1.4 version and a 1.1/jdk5 version just seems 
reasonnable to me.

I'm just thinking about Geronimo which needs a 1.4 JDK compatible source 
base. What should we do? Do we have to "inject" all the new features we 
will pour into 1.1 back to 1.0 ? That's the good question in my mind. I 
don't know if we should tighten ADS developper (I'm thinking of Mina) 
into a JDK version that does not fit their needs, and I don't know if we 
should do it the Tomcat way (having a 5.0/JDK1.4 and a 5.5/JDK5 
versions), which will generate more work for all of us.

Further more, the longer we will wait for this move, the more we will be 
stuck with the user base on old JVM...

I'll vote +1, strongly.
