That's because (I suspect) most of Sun's big customers use their static 
compilers.  On Java speed... I still debug in emacs instead of using Sun 
Studio because the latter is irritatingly slow.  Java may have the 
potential to produce fast code, but I wish that were more evident in the 
performance of Java UI apps I've used.  This may be entirely a problem 
with Swing or whatever, but appearances count.
