/* Test for the contexts in which deprecations warnings should
 * (and should not) be given.  They should be given when
 * o  invoking a deprecated method from a non-deprecated one.
 * o  new X() using a deprecated constructor
 * o  super() to a deprecated constructor
 * o  extending a deprecated class.
 * But deprecation messages are suppressed as follows:
 * o  Never complain about code in the same outermost class as
 *    the deprecated entity.
 * o  Extending a deprecated class with a deprecated one is OK.
 * o  Overriding a deprecated method with a deprecated one is OK.
 * o  Code appearing in a deprecated class is OK.
