Please run the attached test - the following image should appear: red square (100x100) in the center of another one (300x300).

Then please uncomment line
  System.setProperty("sun.java2d.uiScale", "2");
Expectation - scale x2 for both the rectangles. But the inner one is not scaled properly (it seems to be non-scaled at all) - see the screenshot attached (the same for the ellipse shape etc.)

JDK9b121 + Win. 7

Also reproducible on HiDPI screen without applying debug scale flag (Win. 10 + the same JDK9 build).

Causes multiple failures of "ShapedAndTranslucentWindows" tests for awt, swing
