 * @test

 * @bug 4395238 4354003 4387961 4395266

 * @summary A test of many of the new functionality to go into JSSE 1.1

 *      Fixed 4395238: The new certificate chains APIs should really be

 *          returning certs, not x509 certs

 *      Fixed 4354003: Need API to get client certificate chain

 *      Fixed 4387961: HostnameVerifier needs to pass various hostnames

 *      Fixed 4395266: HttpsURLConnection should be made protected

 * @run main/othervm HttpsURLConnectionLocalCertificateChain

 *

 *     SunJSSE does not support dynamic system properties, no way to re-use

 *     system properties in samevm/agentvm mode.
