@aivanov-jdk 
Definitely using Util will be simpler and lesser lines of code.
Then we will be getting a True/False as return value.
Afraid that we will have less info on pixel, color & coordinates like
`Captured pixel (fffeff00) at (0, 0) is not equal to real pixel (ffffff00)`

This being an AWT Robot test, should we add a Swing Util dependency as well?
