Static initializer references subclass

Reports classes that refer to their subclasses in static initializers or static fields.

Such references can cause JVM-level deadlocks in multithreaded environment, when one thread tries to load the superclass and another thread tries to load the subclass at the same time.

Example:

  class Parent {
    static final Child field = new Child();
  }
  class Child extends Parent { }
