Philip Ogren commented on DERBY-4921:
-------------------------------------
I prepared some code that demonstrates the behavior that I ran on the latest
driver (10.9.1.0). I don't see away to attach it so I will just paste it here.
Hopefully, it will render ok.

import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
/**
* to run testClientDriver first start the Derby server with something like:
* java -jar derbyrun.jar server start
*
* to run testEmbeddedDriver change the local variable 'location' to some
directory that exists on your system.
