As the test summary mentioned, it supposed to "Check getGraphics doesn't throw NullPointerExcepton for invalid colors and font"...the closed test was also like it...was applet based which is just converted to use BufferedImage.getGraphics to be a headless test..
Seems [4746122](https://bugs.openjdk.org/browse/JDK-4746122):Failed to load applet fix is about applet,
Once comment in the bug says 

The problem is applet overrides Component.getBackground()/getForeground() to
return null. So SunGraphics2D is created with null params


 so I guess this test is redundant now and we can remove..please suggest..
