Missing jar?

[Patricia Shanahan]

Several programs in qa_refactor import classes from 
au.net.zeus.collection. For example, 
com/sun/jini/start/AggregatePolicyProvider.java contains:

import au.net.zeus.collection.RC;
import au.net.zeus.collection.Ref;
import au.net.zeus.collection.Referrer;
Does this represent a jar I need to compile River? If so, where do I get it?

Thanks,

Patricia
