Sun has worked hard at solving this problem by providing a comprehensive 
test suite. I think they've been reasonably successful at doing that, 
although I regularly read that people still have to tweak for various VM's.

But once again, this is *not* an inherent charactistic of VM's. If, for 
example, one had a comprehensive compiler test suite for various platforms, 
and one prevented calling any that didn't pass it a "D compiler", one could 
do just as well.
