 * @summary Check if swing components present in a window set with opacity less
 *          than 1.0 appears translucent
 * Test Description: Check if TRANSLUCENT Translucency type is supported for the
 *      current platform. Proceed if supported. Show a window containing some swing
 *      components and set it with opacity less than 1.0. Check if the swing components
 *      appear translucent and check if events trigger correctly for the components
 * Expected Result: If TRANSLUCENT Translucency type is supported, the components
 *      should appear translucent showing the background. They should trigger events
 *      correctly
