One can cap the java heap using -Xmx, but that's not the total rss footprint seen by the operating system with tools like top.

So i ask you:
In theory, what is the smallest memory footprint possible for a java program?

The JVM needs some memory to do its work, and how much it uses is unspecified (and differs from one JVM version to the next). It depends on the implementation of the JVM. So your question can't be answered with a simple number.
