Maybe an interface with:
public interface SimpleRealVector {
double getEntry(int i);
int getDimension();
}
will do?

A "clean" solution would be split RealVector in a base interface, which

Yes, that's the plan. the 'new' plexus-utils FileUtils will for example
probably be a slim shim over the commons-io counterpart and just route through.

A common pattern is to introduce an own 'run-its' profile which configures
surefire to pickup those tests.
It's just not good to have tests which in summary takes longer than 3 minutes
to run. This usually leads to developers using -Dmaven.test.skip=true which is
kind of counter productive...

Do I put the test into a separate directory and tell surefire inside the
profile to look into that other dir?
