Please review the fix for JDK 10.
The test fails with or without HiDPI with Exception.
Failed. Execution failed: `main' threw exception: java.lang.RuntimeException: bounds = java.awt.Rectangle[x=74,y=40,width=181,height=185] loc = java.awt.Point[x=274,y=240] background loc = 100, 100 so middle point over background is 264, 232 Oval is not opaque in the middle point (364, 332, java.awt.Color[r=51,g=51,b=51])
The test case creates a class PerPixelTranslucentCanvas which drives from Common class. It has a instance variable OVAL_COLOR. In the constructor, it is calling super class constructor which in turn calls createSwingComponents function which is overridden by PerPixelTranslucentCanvas. This function uses the OVAL_COLOR. The instance variables are loaded before the class construction, but after the super constructor has been called. As the variable is not static, it is not yet loaded and null is used. So this variable should be static, so that it is created on class loading.
There are variables BG_COLOR and FG_COLOR in common class which are static as well.
Also added an addition @run to run the test at HiDPI also like other tests in the same folder.
