Re: ClassCastException in generics

    instanceOfArrayBuffer for file = false

    instanceOfArrayBuffer for good copy = true

 Uncaught Error: java.lang.ClassCastException 

I think that it is a problem for generics. 

GWT will fail its checkcast for any instance of system type (like array buffer or whatever) for any class created other in any context other then $wnd.

JS "new ArrayBuffer(10)" and "new $wnd.ArrayBuffer(10)" has different type from GWT point of view.

Then my next question: 

if GWT generates checkckast as "yze_g$(fileBuffer_0_g$, $wnd.ArrayBuffer)",  where "$wnd.ArrayBuffer" is a type

how can I ask GWT to generate checkckast  to ArrayBuffer, not to $wnd.ArrayBuffer ? 

Thanks
