 * SSLSocket.setUseClientMode() on one or the other of the ends of the
 * connection, expecting an IllegalArgumentException.
 *
 * If the server side of the connection tries setUseClientMode() we
 * see the expected exception. If the setting is tried on the
 * client side SSLSocket, we do *not* see the exception, except
 * occasionally on the very first iteration.
