  /**
   * Tells jvm-dtest that a class should be shared across all {@link ClassLoader}s.
   *
   * Jvm-dtest relies on classloader isolation to run multiple cassandra instances in the same JVM, this makes it
   * so some classes do not get shared (outside a blesssed set of classes/packages). When the default behavior
   * is not desirable, this annotation will tell jvm-dtest to share the class accross all class loaders.
   *
   * This is the oposite of {@link Isolated}.
