This is partly true for the company I work for as well, There it is not so much that we do not want to run 1.5, but that the appserver we use (wls 8.1) does not support using newer jvm's (it doesn't even start trying without anything deployed in it with 1.5). So that would mean migrating to wls 9, which is approx. a 6-7 month project IF decided to do so. It's (partly) my job to give 'advance warnings' on this so once apps that require 1.5 are comming out, we have a platform. Rainer, wouln't these kinds of announcements trigger the company you work for to decide to skip 1.4 and go to 1.5?
