Ok, but I still don't see why DataSource and Driver should not share a
common implementation.
The DataSource should be a JavaBean, the default constructor could
initialize by itself the FBStandAloneConnectionManager, or even better the
Driver self could keep its own instance of the FBStandAloneConnectionManager
and use it to get connections.
Under a certain point of view (it doesn't support JCA) that's what e.g. the
mm mysql driver does (the DataSource just delegates connection creations to
the Driver).
This would make coherent the Driver's behaviour in an unmanaged scenario:
new connections only through the DriverManager which uses the installed
ConnectionManager to allocate them.
