Problem Description
Integer format strings that contain positional arguments result in an IllegalFormatConversionException when passed to String.format(). If the positional part of the format is removed, the call works fine.
Expected Results
Strings with positional should work fine.
Actual results
The strings with positional information are throwing an exception.
Test case
var win = Ti.UI.createWindow();
Ti.API.info(String.format('non-positional: %d', 1));
Ti.API.info(String.format('positional: %1$d', 1));
win.open();

Workaround is to use ".0f" as the format instead of "d":

Closing ticket as the issue cannot be reproduced.
