| static final boolean | isAbstractInterface(java.lang.Class cl)Return true, iff,
1. 'cl' is an interface, and
2. 'cl' and all its ancestors do not implement java.rmi.Remote, and

if all the methods (including those of its ancestors) throw an
exception that is atleast java.rmi.RemoteException or one of
java.rmi.RemoteException's super classes.
