+ * @test
+ * @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.
