I'm seeing an error in web mode that's not showing up in hosted mode.
I initially posted the issue on the GWT-Platform group here:
http://groups.google.com/group/gwt-platform/browse_thread/thread/08bf21467e9f2ec0
.
The gist is that ArrayLists in java throw
ArrayIndexOutOfBoundsException for negative index values and
IndexOutOfBoundsException for index values >= the list size. In all of
GWT's compiled javascript both cases throw IndexOutOfBoundsException.
Here's the offending line in the detailed js output (it shows up in
all permutations):
(index < 0 || index >= 0) &&
java_util_AbstractList_indexOutOfBounds__IIV(index);
Here's the simplest test case I could come up with that produces it:
public void onModuleLoad() {
List<String> list = new ArrayList<String>();
// trickery so the compiler doesn't optimize anything out
Integer i = new Integer("-1");
try {
list.get(i);
} catch (ArrayIndexOutOfBoundsException e) {
Window.alert("caught!");
}
}
The workaround is trivial but I can file a bug for this if necessary.
Thanks for the help!
Tom
