     If your application doesn't use FX, the FX classes and FX libraries
aren't loaded.  They'll use disk space, yes, but although the amount
would have been troublesome twenty-five years ago it doesn't come to
much nowadays.  Let's see <checks>: I can get a 2TB drive for US$63,
which is three thousandths of a cent per megabyte, so space to store
the entire JRE will set you back just over half a cent.  Even at SSD
prices (240GB for US$78) you'll need to scrounge up less than six cents.

     First, I'll second Arne Vajhøj's suggestion that you check the
license for any prohibitions on subsetting.  I'm not sure whether
JavaFX is yet part of the "official" Java or whether it's still
"just along for the ride," but don't rush ahead without checking.

     Second, if you can in fact purge FX and its forty or fifty MB,
be careful not to hurt your arm trying to pat yourself on the back
for saving not quite two-tenths of a cent.
