>      . As a follow-up from the discussion, I've now removed the VM option -Dsun.java2d.opengl=True for the test cases.
>      . In addition, the test cases that were dedicated for OpenGL backend (in open/test/jdk/sun/java2d/OpenGL) have been moved to appropriate directories namely- open/test/jdk/java/awt/image/VolatileImage (or) open/test/jdk/java/awt/Graphics2D.
