Re: Java 1.3 compatible VM for Mac 9?

No, the Apple VM for OS 9 (called MRJ 2.2.5) will only support JDK 1.1.8
and there are no plans to further develop it. Any non-Apple VM's that I
know of only run in browsers, and are older than JDK 1.1.8 (specifically
I am thinking of the Netscape and Microsoft VM's).

However, by adding the 1.1 Swing and Collections classes available from
Sun, I have been able to maintain a large degree of compatibility with
1.3 apps.

In particular, I ported an existing 1.3 app to run on OS 9 (and other 1.1
JRE's). It definitely required some work, but the final product is more
or less the same without major compromises. (Unfortunately, the 1.1
Collections package is still required to run this version on newer JRE's,
because even though they are the same as the 1.2 Collections classes,
they are not in java.util.)

I realize this probably doesn't suit your needs that much, but I'm just
saying that it can be done if it's important for you to have OS 9
compatibility. If you want to see the kind of changes that I made, I can
send you the change log.

Ivan.
