Re: I need some help

I am very familiar with realtime systems, having designed and
implemented them for some years. My request does not go to the nature
of such systems, nor to any questions about their language of
implementation, nor to the silliness of the comparison between voting
systems and flight control systems. My request is merely for a citation
for the given proposition.

By the way, nothing about Java prevents a vendor from writing a cheat
("Trojan Horse" or "trapdoor") into a system implemented using it.
Java's security model is concerned with protecting items in the
environment in which the Java VM runs (e.g. your files) from malicious
Java apps downloaded from untrusted sources (e.g. the web). It is not
concerned with protecting users of a Java program from code that
computes its result (e.g. a tabulation of votes) differently from the
manner in which it is advertised. The latter is much more important to
voting system security than the former.
