The Sun JVM uses a separate memory space for managing Classes (as  
opposed to heap memory used for normal objects). When managing your  
Sun VM memory settings, you want to think about heap memory and  
permgen memory. I don't recall the specifics of how Sun calculates  
your default max permgen setting (I don't have internet access at the  
moment) -- IIRC it's a function based on your physical memory size.
