JDBC doesn't specify any mapping for GIS types, so the JDBC driver doesn't support them "natively". Until such time as JDBC and or the JDK actually ship with support for GIS, you'll have to rely on third-party support (such as OpenMAP), as it would create too many dependencies in the JDBC driver to ship with GIS support out-of-the-box.
