I understand that these sorts of errors are annoying, but they're also extremely rare, which is why I want them to be caught and reported. If I make the viewer "tolerate" such errors, then users will never report them, and they'll never get fixed.
Other VNC viewers may not have the issue because they aren't using JPEG encoding (RealVNC, for instance, doesn't support JPEG) or, for whatever reason, they aren't triggering the same image sequence on the server. In any sense, this is a serious and rare bug. It's something that needs to be fixed ASAP. The BUILDING.txt document explains everything you need to know about building the Mac Java viewer. I think all you'll need is just the Apple Java development package and CMake.
