Why should it be so? I guess the platform dependent code emission code is
err ... not platform independent anyway. Also, if the reference platform is
for instance LLVM, or some other, off the shelf, low-level intermediate
representation, then there is no more platform dependence to take care of at
the JVM level (I suppose)...

The problem of Java written JVM/JIT isn't one of performance.  You can 
theoretically achieve the same performance (although I'm not 100% 
convinced, I'm partially there) especially if you're willing to "extend" 
Java for the purpose of writing Java.

That being said...doing so in a portable and platform independent way is 
actually HARDER in Java than in C (and by C I mean 
C/C++/Objective-C...whatever).  Read the Sable paper...  you'll see what 
I mean :-)
