Bryan Pendleton commented on DERBY-5488:
----------------------------------------

I am fine with the proposed implementation. I think I was getting somewhat confused between
compile-time support and run-time support.

My train-of-thought regarding my reaction was something like: if I am told that a particular 
DB/driver/implementation is JDBC version X.Y, then I expect to look in the Javadocs for 
version X.Y and be able to call those APIs. 

I would not expect to have to use reflection to do so. 

When I look up, e.g., java.sql.PreparedStatement, I expect the "Since:" field to
help me with this comprehension. This doesn't work perfectly; for example, when I go to:
http://download.oracle.com/javase/6/docs/api/java/sql/PreparedStatement.html#setRowId(int, java.sql.RowId)
I see that the setRowId() method is marked "Since: 1.6", and I have to know that this actually means
"JDBC 4.0", but once I accomplish that, I know that I am calling a method that requires JDBC 4.0.

I note that when I go to http://www.oracle.com/technetwork/java/javase/jdbc/index.html which
is presumably the base of all the JDBC spec definitions, I am referred to JDBC documentation
for the base JDK, not by JDBC version number. That is, it says: 

        JDBC documentation: J2SE 1.4.2 | J2SE 5.0 | Java SE 6

At any rate, returning 4.1 seems fine to me; I think I am expressing a related, but independent,
confusion that affects the life of the JDBC application programmer :)

                
> Add remaining JDBC 4.1 bits which did not appear in the Java 7 javadoc.

> In addition to the JDBC 4.1 bits which were visible in the Java 7 javadoc, a couple other items appear in the JDBC 4.1 Maintenance Review spec. This spec has been published on the JCP website at http://download.oracle.com/otndocs/jcp/jdbc-4_1-mrel-eval-spec/index.html. I will attach a functional spec for the remaining bits.
