 * @bug 4717766
 * @summary 1.0.3 JsseX509TrustManager erroneously calls isClientTrusted()
 * @run main/othervm ClientServer
 *
 *     SunJSSE does not support dynamic system properties, no way to re-use
 *     system properties in samevm/agentvm mode.
 * @ignore JSSE supports algorithm constraints with CR 6916074,
 *     need to update this test case in JDK 7 soon
 * @author Brad Wetmore
 *
 * This problem didn't exist in JSSE 1.4, only JSSE 1.0.3.  However,
 * this is a useful test, so I decided to include it in 1.4.2.
