Re: [jbosscache-dev] Let's make 3.0 backwards compatible

After a good nights' sleep and a fresh mind, I've had a rethink and have a potential solution. Tell me what you guys think, this will apply to both 3.x -> 2.x compat, 3.x -> 1.x compat and 3.x -> 2.x compat. 1. For each release, create a "namespace-safe" package. E.g., for 3.0.0, create jbosscache-core.jar as well as jbosscache-core-namespace- safe.jar. This would be constructed using jarjar, where org.jboss.cache.* is translated to org.jboss.cache.3.* (or org.jboss.cache.2.*). 2. Create new distributions for each compatibility layer. E.g., for 3.0.0, a jbosscache-core-2.x-compat.jar and a jbosscache-core-1.x- compat.jar. These modules would depend on the "namespace-safe" module, and provide a delegation layer emulating either 2.x or 1.x interfaces. The upside is that the compat jar can be used as a drop-in replacement for 1.x, but it will not expose new APIs and such. So if someone wants 1.x compatibility AND be able to use new APIs, then they'd be stuck. But IMO if they want new APIs then they're rewriting code anyway and could just use the new jars. WDYT?
