Branching off on the backward compat thread, what do people think about an adapter package that could bridge between code written for 1.x and 2.x/3.x jars? We could create a compat package that offers 1.4 compat interfaces, and delegates these to a 2.x or 3.x instance. The challenge will be classloading, but this can be handled internally in this package, using a separate classloader to load 2.x classes. Thoughts? -- Manik Surtani Lead, JBoss Cache manik(a)jboss.org
