Compile error on open-xchange-admin

Hey, this is exactly the error I get since this morning. Nothing wrong before, but now it's not working anymore. Did the OX dev team change one of the sources?

Hi I change now to OpenSuse 10.3. Work really well.
I download the OpenSuse10.3 Installer. (Look really good).
But I get a compiler error when compiling open-xchange-admin .

# ant -q -Dlib.dir=/opt/open-xchange/lib install
