Sure. But again jni jars are not arch-independent. They depend on
arch-specific binaries to work. How do you ensure the correct
arch-dependent binaries are present if you dump the jars
in /usr/share/java ? Remember it will expose them to build-classpath and
friends. This is different from the usual arch-dependent code use
arch-independant situation. In fact it's the reverse situation so you
need to do the arch filtering at the jar level.

(I'm tired bow, If I make sense to someone can he reword my
explanation?)
