After some fiddling around it was possible to
make the lib compatible with Java 1.4 again, but
that doen't mean that the Library will stay 1.4
compatible for ever. But for now welcome back
MacOS users sorry for the JDK 1.5 problem.
I will release a new version of the Lib probably with
ID3v1 and ID3v2 support some time later this month
