 * @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.
