I'm trying to move away from using Cloneable, it is generally considered to be a broken API [1]. So I have removed Cloneable from all *internal* classes where they existed (Fqn, InvocationContext, Region, some Commands) but they also exist on public API classes (such as all Configuration elements, Option) so we have to live with it there. But we should keep it to a minimum and make sure we don't use this in future classes. Cheers Manik [1] http://www.artima.com/intv/bloch13.html -- Manik Surtani Lead, JBoss Cache manik(a)jboss.org
