Just in case:
http://article.gmane.org/gmane.os.freebsd.devel.java/11638

It would be cool if Someone could produce a proper solution at last.

>   -V 2011g -d tzgen-java \
>   africa antarctica asia australasia europe northamerica southamerica \
>   etcetera factory backward systemv pacificnew \
>   gmt jdk11_backward
> 
> This gives a few error messages but generates files.

> These files are quite similar to those in /usr/local/jdk1.6.0/jre/lib/zi

> how to test this more thoroughly.
