1. Drag the 'Declaration' view to the right side so that a new stack is created.
2. Now drag the 'Javadoc' view inside that newly created stack and make another stack within it.
3. Now close all three views, 'Problems', 'Declaration', and 'Javadoc', at the bottom.
4. Ctrl+3 > Declaration
5. A CCE will be thrown.
