I have further simplified my test.


        // old method using TextureIO.newTexture
        InputStream streamA = Objects.requireNonNull(CompareLoadMethods.class.getResourceAsStream("viewCube.png"));
        Texture a = TextureIO.newTexture(streamA,false,"png");
        streamA.close();

        // new method using AWTTextureIO.newTextureData
        InputStream streamB = Objects.requireNonNull(CompareLoadMethods.class.getResourceAsStream("viewCube.png"));
        BufferedImage image = ImageIO.read(streamB);
        streamB.close();
        TextureData textureData = AWTTextureIO.newTextureData(GLContext.getCurrentGL().getGLProfile(), image, true);
        Texture b = TextureIO.newTexture(textureData);

Texture 'b' is vertically flipped from Texture 'a'.  What am I doing wrong and how do I fix it?  I hope there's a fix to textureData so that both TextureIO.newTexture calls return the same result.
