I've added a system test, that passes with the proposed fix and fails without it.

Without the fix, the AccessControlException exception prevents the color chooser dialog from showing up, but its window still reports onShowing true and the color can be still changed programmatically. There is an exception logged, but to make the test actually fail, I had to check for the window dimensions.
