As described in the JDBC 4 spec section 3.1.
This addresses new Connection methods added by JDBC 4 which are not addressed by the large object work (
DERBY-796) and EOD work ( DERBY-942). These additional methods are getClientInfo(), setClientInfo(), and isValid(). For the client info calls, we propose to not support the getting/setting of client info properties for release 10.2. Support for this functionality is optional. These properties are used for configuring session-scope, server-side diagnostics which Derby supplies through other mechanisms.
