Package-visible nested class

Reports nested classes that are declared without any access modifier (also known as package-private).

Example:

  public class Outer {
    static class Nested {}  // warning
    class Inner {}          // warning
    enum Mode {}            // warning depends on the setting
    interface I {}          // warning depends on the setting
  }
