AWT Choice doesn't send an event for ItemListener by mouse operation on Linux.
Keyboard can work.

Recreate steps:
1. Create and open a frame with AWT Choice component.
2. Select an item on the Choice.
Even if the item was not the current one, no event was posted.

Evaluation:
This is a regression problem since 12-b17.
There is a chance to update the selected item before condition check.
