 * @summary A compile test to make sure some of the new functionality
 *      is there.  It doesn't actually call anything, just compiles it.
 *
 * 4387949: Need to add Sockets and key arrays to the
 *      X509KeyManager.choose*Alias() methods
 *      chooseServerAlias method is reverted back to accept a single
 *      keytype as a parameter, please see RFE: 4501014
 * 4302197: There's no mechanism to select one key out of many in a keystore.
 * 4396290: Need a way to pass algorithm specific parameters to TM's and KM's
 * 4395286: The property for setting the default
 *      KeyManagerFactory/TrustManagerFactory algorithms needs real name
 * @run main/othervm KeyManagerTrustManager
 *
 *     SunJSSE does not support dynamic system properties, no way to re-use
 *     system properties in samevm/agentvm mode.
