Why doesn't JdbcConnection implement JDK 7?

[Gili]

Hi,

Why does JdbcConnection not implement getSchema() and other methods introduced in JDK 7? I see this in the code:

    /**

     * [Not supported]

     */

/*## Java 1.7 ##

    @Override

    public String getSchema() {

        return null;

    }

//*/

Is there a technical reason support can't be added?

We do implement the JDK7 methods. The /*### stuff is our build
preprocessor we use to make it easier to switch back and forth between
developing on JDK6 and JDK7.

Hi Noel,

I neglected to mention: I am getting "java.lang.AbstractMethodError:
abstract method not implemented" when invoking getSchema() which sounds
like a bug to me. Can you reproduce this on your end using version 1.3.176?

Thanks,

Hi,

The default jar file of H2 is compiled for Java 6, not Java 7. To use the JDBC methods that were added in Java 7, you need to compile H2 using Java 7. But please note that many such new methods are not yet supported (for example getSchema).

Patches for new JDBC features introduced in Java 7 are welcome!

Thomas

Thomas,

Why don't official releases (found on Maven Central) get compiled using Java 7? Can't Java 6 users run such code? If not, how about releasing multiple packages so we can begin benefiting from these features?

JDK 6's end of life was February 2013. Can't we drop support and move all users to JDK 7? See http://www.oracle.com/technetwork/java/eol-135779.html

Thanks,
Gili
