/**
 * This class implements the SunJSSE X.509 trust manager using the internal
 * validator API in J2SE core. The logic in this class is minimal.<p>
 * <p>
 * This class supports both the Simple validation algorithm from previous
 * JSSE versions and PKIX validation. Currently, it is not possible for the
 * application to specify PKIX parameters other than trust anchors. This will
 * be fixed in a future release using new APIs. When that happens, it may also
 * make sense to separate the Simple and PKIX trust managers into separate
 * classes.
