Brian, That is what you get for using the nightly :-) But seriously, thanks for the heads up. This problem is indeed a bug in nc-java. We are working with Jon's group to fix the issue ASAP. In the meantime please use 5.0u2 which does not have this problem. Also, please test your zidv bundle without Internet connectivity to verify it really does what you expect.
