25         This class contains public statics that map directly to the
26         new public statics in the jdbc 4.0 interfaces. By providing
27         an intermediary class with hard-coded copies of constants that
28         will be available in jdbc 4.0, it becomes possible to refer to
29         these constants when compiling against older jdk versions.
30
31         <P>The test <code>jdbc4/JDBC40TranslationTest.junit</code>,
32         which is compiled against jdk16, contains tests that verifies
33         that these hard coded constants are in fact equal to those
34         found in jdk16.
35
36         <P>
37         This class should not be shipped with the product.
38
39         <P>
40         This class has no methods, all it contains are constants
41         are public, static and final since they are declared in an interface.
