Robot fails to click on Mac OS X / Java 7

[caillette]

When running tests on Mac OS X (10.8.4) and Java 7 (1.7.0_21-b12) the mouse pointer jitters over text fields and takes dozens of seconds before it finally clicks on them. The tests don't really fail but become slow enough to prevent from building.

Emmanuel Puybaret (author of 2 books on Java) found the following workaround. The System property resolution should go in a constant but we favored readability.

org.fest.swing.monitor.WindowStatus

@RunsInEDT
private void mouseMove(final Window w, Point point) {
  final int x = point.x;
  final int y = point.y;
  if (x == 0 || y == 0) return;
  robot.mouseMove(x, y);

      && w.getBounds().contains(x, y)) {
