 * @key headful
 * @summary Check if a Choice present in a window set with opacity less than 1.0
 *          shows a translucent drop down
 *
 * Test Description: Check if TRANSLUCENT Translucency type is supported on the
 *      current platform. Proceed if supported. Show a window which contains an
 *      awt Choice and set with opacity less than 1.0. Another Window having a
 *      canvas component drawn with an image can be used as the background for
 *      the test window. Click on the ComboBox to show the drop down. Check if
 *      the drop down appears translucent. Repeat this for Window, Dialog and
 *      Frame.
 * Expected Result: If TRANSLUCENT Translucency type is supported, the drop down
 *      should appear translucent.
