You don't, and you don't need to or want to.  VPATH is not appropriate
for finding derived objects like .class files.  See my web site below
for some information on the uses (and mis-uses) of VPATH.

The find command of course returns the full path to the class files, not
just the file names.  There's no need to use VPATH.
