The network server already does this for some JDBC 3.0 methods that it
needs even when the JVM only supports JDBC 2.0. The methods are
defined in interfaces starting with Engine (for instance,
EngineStatement and EnginePreparedStatement). When the network server
needs to call one of those methods, it casts the Statement object to
an EngineStatement.
