Hi All,


Please review a fix for JDK-8197808: https://bugs.openjdk.java.net/browse/JDK-8197808

Webrev: http://cr.openjdk.java.net/~kaddepalli/8197808/webrev00/


The problem was that by the time Robot tries to read the color on screen, the compositing of the window is not completed, and hence, instead of reading Blue color, it is reading a combination of Blue and Red colors. Increasing the delay by 100 ms made sure that the composition is complete and the color is being read correctly. Also, this happens only on Windows 10.

Apart from this, the test was not cleaning up the windows when it throws exception, so fixed that, and also added all explicit imports.
