So you install to /usr/share/<pkg> as you need to have the ABI in the package name when you don't have something like slots.

If the ABI changes between 1.0 and 2.0, they would be two different packages. This requires of course that there is stuff that requires both versions to be present. Hopefully someone with Debian Java experience can comment on that this one (Hi avdyk , man-di, etc :) ). Regards, Petteri
