java.lang.NoSuchMethodError: com.vaadin.ui.Grid$Column.setRenderer

[OsamaFelFel]

I'm testing the add-on (version 3.0 with vaadin 8.0.1) with the following code,

Button upload = new Button("Upload");
upload.addClickListener(event -> {

    UploadFinishedHandler uploadFinishedHandler = new UploadFinishedHandler() {
        @Override
        public void handleFile(InputStream stream, String fileName, String mimeType, long length, int filesLeftInQueue) {
            System.out.println("UploadFinishedHandler");
        }
    };

    UploadStateWindow uploadStateWindow = new UploadStateWindow();
    MultiFileUpload fileUpload = new MultiFileUpload(uploadFinishedHandler, uploadStateWindow);
    fileUpload.setVisible(true);
});

However the above code generates the below error:
