Hmmm, isn't it possible in Java to invoke a program such that it has no I/O
privileges whatsoever, except to accept arguments from and return a result
to the caller?  In that case, the tournament organizer could send a Java
stub to the participant that communicates securely with the tournament site,
and invokes a local Go program written in Java that (short of hacking the
Java virtual machine) cannot obtain any hidden input.
