if (catch Throwable) catches the Exception but (catch Exception) does not, then the underlying fault is an Error not an Exception. This should only have been thrown if the subsystem believes the whole system is unstable and the world should halt.
See http://java.sun.com/javase/6/docs/api/index.html Its worthwhile understanding the Java Exception mechanism. Its one of the things I think really make Java strong as a development language.
