JVM - is stands for Java Virtual Machine

'HotSpot' is just the mnemonic name of one of Sun's realization for it.

For instance Bea has it's own JVM realization, which they call JRockIT

It should be noted though that that document is over 2 years old, and the garbage collector has had a massive overhaul in 1.4, so parts of that document may be wrong...

Still a good read though :-)
