This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
As Moguluri said, you've not shown us the code of Interface2 and Interface3. So the best guess is there is a getInfo() method in them too with maybe different exceptions in throws clause. But in any case, methods in interface don't have a body, so they are not called. There is only one getInfo() method which has a body, and that is in the OverRideOnMultiInterfaces class, so that will be called.
