I tried all the Client URLs added in the test jdbcapi/checkDriver.java.

With 10.1 server and 10.2 client : behaviour same as before this
patch. (protocol error)
With 10.2 server and 10.1 client: Instead of protocol error, client
throws a SQLException with null message. ij displays:
ERROR      : DERBY SQL error: SQLCODE: -1, SQLSTATE:      , SQLERRMC: null

This does not look so good. It happens because the server is changed
to return null SQLCARD with RDBAFLRM but the old client does not
interpret this null SQLCARD and just throws it out as SQLException to
the caller.
