NullPointer in BaseGraphics.drawTextureVO

[Daniel Zwolenski]

Can anyone tell me what might cause the exception below in Prism?

It's from an app that captures video via a native library (LTI-CIVIL) and
then converts that image to JFX display via:

    BufferedImage buffImage = AWTImageConverter.toBufferedImage(image);
    jfxImage = javafx.scene.image.Image.impl_fromExternalImage(buffImage);
    previewView.setImage(jfxImage);
