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(); } }
