DrawableCompat.setTint() no longer working with appcompat-v7 23.2.1

Setting the tint was previously working in 23.2.0. When I change the version to 23.2.1, the following codes no longer tints my ImageViews.

I have a list of Image view defined as

List<ImageView> statusStage = new ArrayList<>();

and I update the image tint using the method below.

public void setStatusStage(int stageComplete, int colorOn ) {
    for (int i = 0; i < statusStage.size(); i++) {
        ImageView ss = statusStage.get(i);
        Drawable dr = DrawableCompat.wrap(ss.getDrawable());
        DrawableCompat.setTint(dr, colorOn);
        print("stage Complete:" + stageComplete+", "+i);
    }
}

Is the way to setTint different now? What do I need to change in my codes to get it to work for the new version?

The appcompat version with the bug.

compile 'com.android.support:appcompat-v7:23.2.1'
