[Cialug] JAVA version woes.

[Tom Pohl]

Naa, way more important than that :)

I use java for our web applications and at the time, I really needed  
to get a new server running in production like yesterday to take  
stress off the rest of the servers and our normal production config  
didn't cut it because of the bleeding edge version of the hardware.   
Long story short, google saved the day :)

Thanks google, where ever you are!
