Something wrong is with your classloader. It would be great if you
can find the reason, because you are not the only one complaining
about this, however no test case exists. Error messages are stored in
the firebirdsql.jar/isc_error_messages.properties file and are loaded
using classloader that loaded org.firebidsql.gds.GDS class.

See FAQ question 29. We do no guarantee correct work in dialect 1
databases. If you wish to switch to JayBird, convert your database to
dialect 3.
