> My page has an AjaxSubmitLink and the javascript in HTML source
> (wicket-ajax.js, wicket-ajax-debug.js, ... ) for that component is not exists
> because of an exception.
> The exception is thrown in wicket.markup.html.JavascriptPackageResource at
> line 133: ByteArrayOutputStream is created with negative (-1) length.
> The following patch checks the size and creates stream with a not negative
> value. My AJAX link works with it but I did not verified if it is the right
> fix.
