For Jaybird 3 you could do some of these things using
org.firebirdsql.util.FirebirdSupportInfo (although the specific case
above isn't covered by an explicit method).

For Jaybird 2.2, the easiest way is probably DatabaseMetaData:
getDatabaseMajorVersion() and getDatabaseMinorVersion(), or
getDatabaseProductVersion() which produces a string with the full
Firebird version. For this last method you can use
GDSServerVersion.parseRawVersion(String) to parse this string to a
GDSServerVersion, which gives you limited functionality to compare
versions. There are other ways, but those are not easily accessible when
using FBWrappingDataSource.
