When I upgraded to Snow Leopard, Safari and Vuze mysteriously started crashing. When I looked at the crash logs, I found that some Java bundle was causing the problem, so I deleted it with the intention of reinstalling it. What happens now is that I can access the System Prefs page for Java, but I can't run Java apps in Safari because it displays an error saying that the Plug-In bundle isn't installed. If you can tell me how to get things working again, that'd be great.
