Maybe this is more of a dev question? I'm thinking of using some JDK1.6 classes such as java.util.NavigableMap in JBossCache. Some classes in 1.6 are already part of the backport. (This could easily be done without the 1.6 compiler.) I am a little curious if there's any interest in having this? The refactoring would essentially to rename ClassRedirectEditor to ClassRedirectEditor15, then create a similar ClassRedirectEditor16. (Suggestion on names?) Then create a WeaverConfiguration, which exposes a factory method to return the appropriate editors or whatnot for the configuration.
