50 * SslRMIClientSocketFactory
52 * This class implements an RMIClientSocketFactory for SSL sockets.
53 * it uses the default SSLClientSocketFactory.
55 * This class can optionally use the following system properties, if set:
56 * <code>javax.rmi.ssl.client.enabledCipherSuites</code>
57 * <code>javax.rmi.ssl.client.enabledProtocols</code>
59 * These properties will specify a list of SSL/TLS cipher suites and protocols,
60 * respectively, to enable on the created sockets.
62 * Both properties should consist of a comma-separated list.
