javax/swing/RepaintManager/4939857/bug4939857.java fails with "To many paints: 3"

These tests will fail whenever they happen to run on a system with D3D enabled so they need to be problem listed for windows.
We don't want to run them with D3D turned off since for at least the open one it is specifically intended to test D3D.
