We had this bug some time ago. Which version of JayBird do you have? JayBird
1.5.4 should work correctly. Please test it and report your results here.

If you look in the source of the FBManager, you will see that it uses
exactly that call. There is a GDSFactory responsible for instantiating
appropriate GDS implementation depending on the type you specify.
