Sorry, I thought you'd said that this problem only appeared on linux.

For the Sun JDK, there shouldn't be any other values, because they are
the only platforms they support. Annoyingly, there's no good way of
finding out which platform we're running (I was hoping
java.lang.System.getProperties() would help, but it works in terms of
processor type, not OS type).

No idea what the APPL one does; I only have the JRE on my Mac at the
moment.

I'd be more inclined to believe that it was written by someone who
wasn't very good. Never ascribe to malice what can be explained by
incompetence, particularly in the case of Java.

(JNI was based on work done by Netscape.)
