Possibly unintended overload of method from superclass

Reports instance methods with the same name and the same number of parameters as a method in a superclass, but where at least one of the parameters is of a different incompatible type.

In this case, the method in a subclass will be overloading the method from the superclass instead of overriding it. If it is unintended, it may result in latent bugs.

Example:

public class Foo {
  void foo(int x) {}
}

public class Bar extends Foo {
  void foo(Number x) {} // Method 'foo()' overloads a compatible method of a superclass,
                        // when overriding might have been intended
}

Use the option to choose whether the inspection should also report cases where parameter types are not compatible.
