Is the underlying object actually an ArrayBuffer? The return value is
supposed to be either an ArrayBuffer or a String depending on how you
invoke the reader API.
It seems to me that any methods which might throw CCE because of this
should actually return null, e.g.
class FileReader {
public @JsOverlay ArrayBuffer getArrayBufferResult() {
Object result = getResult();
return result instanceof ArrayBuffer ? (ArrayBuffer) result : null;
}
public native Object getResult();
}
