An SslRMIClientSocketFactory instance is used by the RMI
runtime in order to obtain client sockets for RMI calls via SSL.

This class implements RMIClientSocketFactory over
the Secure Sockets Layer (SSL) or Transport Layer Security (TLS)
protocols.

This class creates SSL sockets using the default
SSLSocketFactory (see 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 createSocket(String,int)
method; in that case, equals and hashCode may also need to be overridden.

If the system property
javax.rmi.ssl.client.enabledCipherSuites is specified,
the createSocket(String,int) method will call 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.

If the system property
javax.rmi.ssl.client.enabledProtocols is specified,
the createSocket(String,int) method will call 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.

An SslRMIServerSocketFactory instance is used by the RMI
runtime in order to obtain server sockets for RMI calls via SSL.

This class implements RMIServerSocketFactory over
the Secure Sockets Layer (SSL) or Transport Layer Security (TLS)
protocols.

This class creates SSL sockets using the default
SSLSocketFactory (see SSLSocketFactory.getDefault()) or the default
SSLServerSocketFactory (see SSLServerSocketFactory.getDefault()) unless the
constructor taking an SSLContext is
used in which case the SSL sockets are created using
the SSLSocketFactory returned by
SSLContext.getSocketFactory() or the
SSLServerSocketFactory returned by
SSLContext.getServerSocketFactory().

When an SSLContext is not supplied all the instances of this
class share the same keystore, and the same truststore (when client
authentication is required by the server). This behavior can be modified
by supplying an already initialized SSLContext instance.
