As the error says it is not implemented. You could also have checked the
sourcecode. It will be (is) implemented in Jaybird 2.2

The method isValid() was introduced in JDBC 4, I would simply use a
validation mechanism that was used by most if not all connections pools
that were developed before JDBC 4 (eg fire off a simple query).

May I ask why you are implementing your own connection pool, as Firebird
comes with its own connectionpool and there are also connection pool
solutions like c3po and dbcp.
