devel/jakarta-ant ?

I agree... What is the policy regarding such major changes in ports ? I
mean it will make a lot of ports deprecated and broken. So we should
provide bsd.java.mk 2.0 together with all Java ports patches IMHO.

I think we've got something here: use space separated preferences (in the
right order) for all JDK/JRE properties. So no more "+" (e.g. "1.3+") but
instead an explicit list of versions...

You're right.

Looks like we're progressing with bsd.java.mk... Any feedback from other
Java porters ?
