As Jon said in one of previous letters -- IDEA 3.0 is distributing
with jdk 1.4. So, error can only be related to that its classes were
compiled with jdk 1.4. Since 1.4 and 1.3 are not forward compatible, so
it won't be executed under 1.3 at all. I think you need to check things
related to your attempts with jdk 1.4 again. It just should work. Or fail,
but with different error. :)

Bissell, Tim
Yes, Idea 3.0 will only work with JDK 1.4.1_01 (not 1.4.0, not 1.4.1), and
fails exactly the same way when run with JDK 1.3.1 on MacOS X.
I really like Idea (18 years of using Emacs as my code editor, Idea was the
first Java IDE to tempt me) but I can't help feeling that IntelliJ have shot
themselves in the foot by making 3.0 run under 1.4.1 only, _and_ removing
the Idea 2.6 download at the same time...
