If I understand you correctly the issue is:

   - When using Layer B streaming, you want the Network Server to be
     able to use the new JDBC 4 methods for lengthless streaming.
   - The problem is that the JDBC 4 methods is not directly available
     to the NetworkServer if using older run-time libraries (e.g., Java
     SE 5).

Since the implementation of the JDBC 4 methods will be part of
derby.jar regardless of which JVM you are running on, I would guess it
is just a question of how to make them available to the network
