<Swing Dev> [9] Review Request: 8177766 [TEST_BUG] JPopupMenu tests fails intermittently

[Sergey Bylokhov]

Hello,
Please review the fix for jdk9.

The problem is that these tests shows popup menu and expects that some specific menuitems will be selected after keyboard navigation. But some other test in the javax/swing/JPopupMenu/** moves the mouse to some specific position, which causes an auto-selection(in Aqua Look&Feel) of the menu item and wrong final test result. Note that if the tests are executed alone it is always passed(if the mouse is not under popup menu).
