since Storage extends UserPrefsStorage and AddressBookStorage, a triangle and a solid line should be used to indicate the inheritance.
In the arrow from Storage to AddressBook storage, the solid line extends into the triangle.
A triangle is missing from Storage to UserPrefsStorage.
I have circled these regions in the screenshot below for ease of referral.
1 is merely cosmetic, but the diagram does not show the inheritance relation between Storage and UserPrefsStorage because of problem #2. Because of this I classify the bug as severity.Low (as opposed to severity.VeryLow)
