We created a branch before the Java 1.5 changes were started:

I think the new Java5 stuff in trunk should be released as IO 2.0 - so
we could release a IO 1.5 version that is for JDK 1.4. Having said
that JDK 1.4 is so old now I don't really think we should bother
supporting it and just focus on getting a release of the latest stuff
