You won't get any argument from me that the results make little sense. At
the time of the test, I was comparing commercial Java platforms, not
compilers: building the test with two different compilers was a chance
occurrence and the observation of a difference was a total surprise.
I didn't delve into the code itself (compiler behavior wasn't relevant to
my inquiries), and I haven't since revisited the problem with more recent
compilers.

Wasn't there considerably less coordination with Sun in the 1.2.2 days
than there is now?
