Review comment:
To generate relative links, have you considered to use `-link` (as the
original ant task does so) option instead of `-linkoffline` ? The first version
of "renderJavadoc" had also used `-link` option with relative file paths before
we changed it to absolute urls. (I'm not sure if it makes sense here and have
no strong feeling with that, but `-link` seems to be more safe since with the
option javadoc tool checks if the files to be linked exist on the local
machine.)
