You are almost certainly using a jdk 1.3 with an interclient compiled for
1.2. You can compile it yourself - there is an ant script at firebird that
will compile the java even on windows - or wait a couple of days until
firebird puts out a couple of precompiled versions. Borland has allegedly
supplied a compiled for 1.3 version also, as have others, but I don't know
where they are.
