as others have noted java.exe is a dos program, not a cygwin
program (a fact I really hate). Dos programs are not used to
having a shell do globing for them, so they all do it them
selves (nothing like forcing everyone to reinvent the wheel).

as you've noted however double quoting the string prevents it
being globed. That's a dos mentality though, so what you need
the input of the dos program to be is the equivalent of this
char[]: {'"','*','"'}  (actually you'll want a '\0' on the end
too....)

when you run from cmd.exe that's trivial, but you're running
from bash, a REAL POSIX SHELL, which has globing built in.
So you've got to escape out any characters that are part of
the globing formula in cygwin in order to get just the right
stuff passed on to java... both " and * are part of that, so:

java someclass \"\*\"

ugly, ain't it? Makes you wish you had a java.exe that was a
real cygwin executable doesn't it? Do me a favor... call up
your nearest IBM representative and ask for it, or drop a note
into their emailbox over at ibm.com/java and ask for it. (that
goes for anyone who's interested in this btw, just don't tell
'em I sent you. ;)
