Can you point me to something? Anyways, I ended up just making setSeed/nextByte synchronized, hopefully that works for you. Also, I added some new stuff so that it initially pulls from "/dev/urandom" if it is available. So, if you experience anything strange, holler. > hth, > =jr thanks! tim _______________________________________________ kaffe mailing list [EMAIL PROTECTED] http://kaffe.org/cgi-bin/mailman/listinfo/kaffe
