 * @deprecated RMI support is deprecated and will be removed in a future version of Jackrabbit; see <a href=https://issues.apache.org/jira/browse/JCR-4972 target=_blank>Jira ticket JCR-4972</a> for more information.
 * <p>
 * Factory interface for creating remote adapters for local resources.
 * This interface defines how the local JCR interfaces are adapted to
 * remote JCR-RMI references. The adaption mechanism can be
 * modified (for example to add extra features) by changing the
 * remote adapter factory used by the repository server.
 * <p>
 * Note that the {@link ServerObject ServerObject} base class provides
 * a number of utility methods designed to work with a remote adapter
 * factory. Adapter implementations may want to inherit that functionality
 * by subclassing from ServerObject.
