Not sure this might be the best place to ask since this question has alot to do with the inner workings of Apache OpenJPA. But maybe someone here knows.

Looking into org.apache.openjpa.jdbc.kernel.exps.PCPath.java you could find Action inner class wich defines a series of static fields.

This one has me a bit lost(it all does, but this one is the one giving me headaches at the moment):

public static final int UNBOUND_VAR = 5;

Can anyone explain this to me?
