if that page should "help" Debian users, why do you use examples from other distributions? If you want to "help", why don't you differentiate between java versions, gcj versions and different releases? Did you check with recent versions of the these implemenations? Why start that page with "why do [...] implementations suck" at all?
Matthias,you found the misleading content, good. :-) That page is not for helping anyone. It was never claimed to be.
