We are working on both. The problem is that JAXB support for new JDK 1.5
language features is being handled by the JAXB 2.0 specification, which
is being actively developed by the JAXB expert group.
Even when JAXB 2.0 is released, it will still need to be able to generate
code that will run on pre-JDK 1.5 VM's. JDK 1.5 language extensions will
probably require compilation switches and schema customizations to support.

As far as we know, JAXB 1.0.x is compatible with JDK 1.5 today. Are you
experiencing errors using JAXB with JDK 1.5 or is it just that you don't
like seeing all the warning messages?

There is no public timetable for its release, but I wouldn't expect it to
be "around the corner".
