Does not work with JodaTime

[michail-prusakov]

Consider the unit test below. The test fails with NotSerializableException. However if i switch to java serialiazation mechanism everything works as expected.

import java.util.List;

import org.apache.jdbm.DB;
import org.apache.jdbm.DBMaker;
import org.joda.time.DateTime;
import org.junit.Test;

public class JDBMTester {

@Test
public void testJodaTime() {
    DB db = DBMaker.openFile("tmp1").make();
    List<DateTime> list = getList(db, "list1");
    list.add(new DateTime());
    db.commit();
    db.close();
}

private <K> List<K> getList(DB db, String name) {
    List<K> result = db.getLinkedList(name);
    if (result == null) {
        result = db.createLinkedList(name);
    }
    return result;
}

}
