Actually for me Sun's java and GCJ take about the same at the default settings
(well for GCJ compiled at
-O3).
Now if I change Sun's java to use the server tuned JIT, Sun's java is 2 seconds
while GCJ is still 4.5 or so.

This with keeping and printing out the return value for nextDouble.
This might be startup/shut down time taking into account.
