Douglas, I don't understand why you are seeing any errors in the latest Java 8. I am convinced that everything functions well when you use the Java 8. I don't doubt that you are seeing errors in Java 8, but I suspect that it is off-topic to discuss the details of the graphics configuration, canvas, and other things in this special situation. Maybe you are having some kind of general problem in the local build environment such as the "unclean" environment in which the Java has created multiple directories with the different library files or something that looks like we are seeing ghosts.
