Umm...Garbage Collection over NON contiguous nGB of HEAP?  No...no thank 
you. 

Parallel collection over nGB of non-contiguous heap would be VERY 
amusing.  Before 64-bit components became very cheap most folks picked 
Sparc/Solaris for enterprise Java.  Also Java's parallel GC wasn't 
stable until 5.0 anyhow so one could argue that 5.0 was the first 
"enterprise ready" release with some credibility.

Picture of Java memory:

Java is a sucky language but the VM memory management  and JIT stuff is 
really sound.
