Yup. I modified the Zip task (from which Jar inherits) to allow updates.
If you get hold of the latest sources for 1.4, I believe it should be in
there - you just need update="true" as a parameter along with the normal
manifest specification. I think that should be enough... let me know if
you have any trouble with it.
