Parameter type prevents overriding

Reports parameter types of a subclass method that have the same name as the parameter type of the corresponding super method but belong to a different package. In these cases, the subclass method cannot override the super method.

Example:

public class A {
 public void method(Object o) {}
}

public class B extends A {
 public void method(Object o) {} // warning on parameter type
 class Object {}
}

After the quick-fix is applied:

public class A {
 public void method(Object o) {}
}

public class B extends A {
 public void method(java.lang.Object o) {} // new parameter type
 class Object {}
}
