Hmm, odd. I've just updated the one at that URL in case I rewrote it and
the following works for me:
mkdir -p debian/test
cp /usr/share/java/ant-1.6.jar debian/test
touch debian/control
dh_javadeps -p test
cat debian/test.substvars

and you assume the program nicely handles this case? I think anything
which causes the JVM to throw an exception failing to load a class
requires a depends. (not that my code above does this, it's a bit of a
hack and is likely to over-depend)

Hmm, that feels totally wrong to me. Possibly a --prefer= parameter?
