/**
 * Tells jvm-dtest that a class should be shared accross 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}.
