/**
 * <p>An <code>SslRMIClientSocketFactory</code> instance is used by the RMI
 * runtime in order to obtain client sockets for RMI calls via SSL.</p>
 *
 * <p>This class implements <code>RMIClientSocketFactory</code> over
 * the Secure Sockets Layer (SSL) or Transport Layer Security (TLS)
 * protocols.</p>
 *
 * <p>This class creates SSL sockets using the default
 * <code>SSLSocketFactory</code> (see {@link
 * SSLSocketFactory#getDefault}).  All instances of this class are
 * functionally equivalent.  In particular, they all share the same
 * truststore, and the same keystore when client authentication is
 * required by the server.  This behavior can be modified in
 * subclasses by overriding the {@link #createSocket(String,int)}
 * method; in that case, {@link #equals(Object) equals} and {@link
 * #hashCode() hashCode} may also need to be overridden.</p>
 *
 * <p>If the system property
 * <code>javax.rmi.ssl.client.enabledCipherSuites</code> is specified,
 * the {@link #createSocket(String,int)} method will call {@link
 * SSLSocket#setEnabledCipherSuites(String[])} before returning the
 * socket.  The value of this system property is a string that is a
 * comma-separated list of SSL/TLS cipher suites to enable.</p>
 *
 * <p>If the system property
 * <code>javax.rmi.ssl.client.enabledProtocols</code> is specified,
 * the {@link #createSocket(String,int)} method will call {@link
 * SSLSocket#setEnabledProtocols(String[])} before returning the
 * socket.  The value of this system property is a string that is a
 * comma-separated list of SSL/TLS protocol versions to enable.</p>
