Re: Packages that require Java 2 ?
Okay, not to throw a proverbial spanner in, but:
One point to note is that j2sdk1.3 and j2re1.3 are not yet in debian at all.
I believe (correct me if I'm wrong) that a package in debian can't depend on
a package outside of debian.

If you're using /usr/bin/java you need to be careful since it may point to
some other JVM and the "java -version" outputs are not at all consistent and
sometimes don't even reflect the JDK version. See below for sample output
from different JVMs.
As for $JAVA_HOME, one must remember that policy (10.9) dictates that you
should not depend on any particular environment variable(s) being set. So
there should be graceful (and correct) behaviour for the case where
$JAVA_HOME is undefined.
