At the moment we ship JDBC in two halves. Core JDBC
functionality is delivered in the J2SE platform, but an unbundled
extension delivers later APIs.

This separation is confusing to developers. I propose
we bundle the whole of JDBC 3.0 into core, so that
the entire JDBC API is available in the core J2SE platform.

This feature is dependent on 4290525: "Bundle JTA API"

JDBC is being developed under the JCP as JSR-054.
