Removing unused methods shouldn't be too difficult for an automated tool
to do, assuming you're not using reflection. Removing unused classes
is rather tougher, because it's really quite hard to tell if a class
is unused. Just because you never explicitly instantiate a class does
not mean that it doesn't get instantiated though something you do,
or because of the settings of various system properties and whatnot.
(For example, anybody who can set the system properties for a VM can
make the JDBC code instantiate arbitrary JDBC drivers, and perhaps other
things too, if you're malicious.)
