Inner class referenced via subclass

Reports accesses of inner and nested classes where the call is qualified by a subclass of the declaring class, rather than the declaring class itself.

Java allows such qualification, but such accesses may indicate a subtle confusion of inheritance and overriding.

Example:

class Super {
  static class Inner {}
}

class Sub extends Super {
  void test() {
    Sub.Inner s = new Sub.Inner(); // 'Inner' class is declared in 'Super' class, but referenced via 'Sub' class
  }
}

After the quick-fix is applied:

class Super {
  static class Inner {}
}

class Sub extends Super {
  void test() {
    Super.Inner s = new Super.Inner();
  }
}
