please review the fix
for the issue

The JDK-8041896 [1] fix consists of two part: actual fix in 
LWChoicePeer.java and unrelated improvements in AquaComboBoxPopup.java.
Changes in AquaComboBoxPopup.java was introduced to remove popup window 
blinking(it shows for about 0.1 sec and then closes).
However this introduce another regression: popupMenuWillBecomeVisible 
handler is not called for empty combobox.

This fix simply reverts AquaComboBoxPopup.java to its previous behavior.
