The danger with that is it allows other uses of jdk6 APIs to sneak into the code. If we're going to do that I suggest having a build target that can compile with jdk5 any modules that don't need the JDBC 4.0 APIs. That target wouldn't be the default build target, since it would force everyone in the community to have 2 jdks configured just to build. But it can be run periodically, and definitely before release, as a QA measure to catch jdk6 API leakage.
