Eclipse Debug mode ClassNotfound Exception

When you run a Java application in Run mode, it's working. But, if you run in debug mode you are getting "ClassNotfound Exception".

Then navigate to Eclipse -> Windows-> Show view -> other -> Type "breakpoint" and select breakpoint

In the Breakpoint view, unselect the checkbox of "ClassNotfoundException: Caught and Uncaught"

and Debug again... It should work!!!
