Since JDK8 b87 the percentage values in CSS radial-gradient behave different. I've created a led control that contains a Region called highlight. This Region should be filled by a radial-gradient via CSS. The following CSS code worked in JDK7 and up to JDK8 b86:

-fx-background-color: radial-gradient(center 15% 15%, radius 50%,
                                                    rgba(200, 194, 208, 0.8) 0%,
                                                    transparent 100%);


Since JDK8 b87 I have to write the following code to get the same result:

-fx-background-color: radial-gradient(center 70% 70%, radius 80%,
                                                     rgba(200, 194, 208, 0.8) 0%,
                                                     transparent 100%);

Please find the modifications in the led.css file.

As you can see the percentage values for center and radius are completely different. To get an idea of what I'm talking about please find two screenshots (expected and current visualization) here:
