A DESCRIPTION OF THE PROBLEM :
There is an obvious problem in the following source file

* jfx/modules/javafx.graphics/src/main/java/javafx/scene/shape/Shape.java

    void setMode(NGShape.Mode mode) {
        mode = mode; // -> this.mode = mode;
    }

This implementation is considered to be working differently than expected.

If you fix this issue, you will be able to use the test I attached in JDK-8229264
The COPY mode of the blend mode works correctly.
I have confirmed this.




STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
1. run the tests attached to JDK-8229264
Check the rendering result of COPY mode. 2.

The following screenshot may be helpful.
