Hi Thorsten,
This is due to the new features in the Javadoc 5.0 Doclet API (added support for generics, enums, varargs, annotations, and annotation types). Unless this is fixed in cvs, you'll have to add some 28 wrapper methods ;) -- which is, however, a very straightforward task (including comments, the resulting diff is less than 8kb in size).
After that, the resulting build worked...
