The JavaDoc says IndexOutOfBoundsException, so you shouldn't expect a more specific exception.
BTW, coding with exceptions is kind of an anti-pattern in JS (because it's faster to check for good values beforehand than rely on exceptions being thrown when bad values are passed in); this is kind of a shift from "standard" Java development, but it's basically the same, and even stronger, in GWT development: the Java runtime emulation does not necessarily throw exceptions; sometimes you'll have a JavaScriptException instead (this is even more true when you enable a few optimization switches, like disableClassCastException). The rule of thumb is: do not count on exceptions being throw the same as in a Java VM. You writing Java, you're reading Java, you're using Java tools, but you're developping JavaScript running in a browser! That's to say, it's highly likely that such a bug report would be closed as WontFix. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
