This was discussed previously and based on the usage it seemed like a  
reasonable approach.  If someone has an all Java alternative that  
would be excellent.  Rather than speculate on where things might fail  
I'd rather since it hasn't broken anything (yet) I think it would be  
better to focus on the specific areas where it is broken.  To date  
I'm unaware of any.
