/*
Here is the old description for the test.

This bug occurs in jdk <= 1.1.6, 1.2b3. The problem is that key press
and release events will not be delivered to a choice component with
the focus if the mouse is over another component (of any type);

This bug occurs in Motif and was fixed in the native code.

1. Set the focus on choice component 1 by selecting an item.
2. Move the mouse over choice component 2, BUT do not set the focus on it.
3. Type some characters e.g. 'a', 'b' etc.
4. Verify by the console output that all the key events are delivered to
   choice component 1, not 2. If all the key events are delivered to
   choice 1, the test passes.
