Example:

Interface ISomething {
 public Class<? extends MyClass> getSomething();
}

Implemention:
Demo implements ISomething {
 public Class getSomething(){ return .... }
}

I think, a warning should appear when you try to remove the Generic Type.

javac -XLint:

warning: getSomething() in Demo implements getSomething() in ISomething; return
type requires unchecked conversion
found: java.lang.Class
required: java.lang.Class<? extends MyClass>
