As far as not catching checked exceptions goes, this is actually possible in the Java language as well since the language allows throwing a generic type parameter. It's pretty difficult to do by accident though, and does at least give a compile warning. public class Dangerous { public static void main (String ... args) { Dangerous.<RuntimeException>throwUnchecked(new IOException("Forgot to catch me!")); } static <T extends Exception> void throwUnchecked(Exception e) throws T{ throw (T) e; } }
