This is not allowed because on pretty much all unixes one can see everyone
else's command-line arguments; hence, the passphrase could be seen by any
other user on the system.

The general way of passing in a passphrase to GnuPG is to do so via a
handle specified in the passphrase-fd option; I don't know if you can
accomplish this with Java though.  There are Perl modules that allow you
to accomplish this farily easily, though.
