This change fixes the exact issue that is reported in [JDK-8284654](https://bugs.openjdk.java.net/browse/JDK-8284654).

But I observed another issue that occurs with this change.
Steps:
1. Run the sample attached to [JDK-8284654](https://bugs.openjdk.java.net/browse/JDK-8284654).
2. Click button One and Two both once
3. Re-arrange both the windows such that they are visible.
4. Click the button "Click here" in Window Two: Error dialog will be displayed
5. Click anywhere in Window One
6. Close the Error dialog
 => Observe that Window One gets the focus and not Window Two.

I think the expected behavior here should be: After closing a dialog the Focus should return to its parent window.
