/**
 * Typically used as the nested exception of a
 * {@link java.rmi.ConnectIOException} if the constraints for a remote call
 * cannot be satisfied. Such an exception can be thrown at the point a remote
 * method is invoked for a variety of reasons, including:
 * <ul>
 * <li>A client requirement is not supported by the server.
 * <li>A client or server requirement conflicts with some other client or
 * server requirement.
 * <li>A client or server requirement cannot be satisfied by the proxy
 * implementation.
 * <li>The local subject that would be used for authentication does not
 * contain sufficient credentials to satisfy a client or server requirement.
 * <li>For a client or server requirement, the proxy implementation does not
 * implement any algorithm in common with the server (for example, because
 * the proxy implementation only uses algorithms that are available in the
 * client environment rather than downloading algorithm implementations).
 * <li>A delegated remote call is being attempted, and the current time is
 * either earlier than the granted delegation start time or later than the
 * granted delegation stop time.
 * </ul>
