With the current state of affairs, it is conceivable that a single-event upset could cause an IF_ICMPNE byte code to be flipped into an IF_ICMPLT without this being detected by ZipFile or the byte code verifier. Similarly a constant could be changed giving a candidate in an election 4096 extra votes, which is what seems to have happened in Belgium in 2003: https://en.wikipedia.org/wiki/Electronic_voting_in_Belgium Eirik :-)
