[9] Review request for 8057893 JComboBox actionListener never receives "comboBoxEdited" from getActionCommand

[Alexander Scherbatiy]

Hello,
Could you review the fix:
  bug: https://bugs.openjdk.java.net/browse/JDK-8057893
  webrev: http://cr.openjdk.java.net/~alexsch/8057893/webrev.00

  This is a regression from the fix 8019180.
  The event source should be compared with the ComboBoxEditor editor 
component.

Thanks,
Alexandr.
