Hi :)  
I really liked this answer and i think we need an FAQ page about java because 
the issue keeps cropping up.  It seems a lot of people here each know about 
different problems with java and it would be good to collect together some of 
the issues and how to work around them.  

So, i made the page
https://wiki.documentfoundation.org/Faq/Java
and am about to copy & paste Stuart's email into the page.  Please feel free to 
edit to make the page more useful.  

Regards from
Tom :)
