There was no missing class. The class that was being loaded was
org.firebirdsql.jdbc.FBDriver but the error could have been associated with
any class needed by that class. Since the error was NoClassDefFoundError
rather than ClassNotFoundException, I thought that it might be a mal-formed
class text. As I said, recompiling with the Sun 1.4.1_01 compiler made the
problem disappear.
