<AWT Dev> [9] Review Request: 8157320 The CheckboxMenuItem can not be selected

[Sergey Bylokhov]

Hello.
Please review the fix for jdk9.

The fix for JDK-6191390 [1] does not take into account that the 
action(final long when) method is overridden in the 
XCheckboxMenuItemPeer.java and after JDK-6191390 it is never called.

In the fix it is updated properly.
