Bug 24929 quick fix: make exception more general [quick fix]
public class DD { void fs() throws MalformedURLException { f(); f1(); } void f() throws IOException{ } void f1() throws MalformedURLException{ } } it'd be cool if qf noticed that it can change the throws clause in fs() to throws IOException (change, not add)
