OpenJDK: JVM and Multicore CPUs

[David Herron]

I suggest bringing this question to the hotspot mailing list.  And, yes, 
it does handle multithreading (e.g. java.lang.Thread) and spreading work 
over multiple processors or cores.  That's one of the reasons the 
Niagara based systems (T2000 etc) get such great performance, as I 
understand it, but don't trust me I'm not a hardware guy.
