This is true if you use the -depend option on javac. I use this all
the time. The strange part is that javac will "touch" all of the
class files as needed when this happens. Also, with -O it will end
up having to compile more than you thought due to some inlining.
Jikes does this a bit better (and it is sooo much faster that you
may not even notice if it were recompiling all files)
