## Interface RMIFailureHandler

-     public interface RMIFailureHandler

  An `RMIFailureHandler` can be registered via the `RMISocketFactory.setFailureHandler` call. The `failure` method of the handler is invoked when the RMI runtime is unable to create a `ServerSocket` to listen for incoming calls. The `failure` method returns a boolean indicating whether the runtime should attempt to re-create the `ServerSocket`.
  Since:
    1.1

    - #### failure

          boolean failure​(Exception ex)

      The `failure` callback is invoked when the RMI runtime is unable to create a `ServerSocket` via the `RMISocketFactory`. An `RMIFailureHandler` is registered via a call to `RMISocketFacotry.setFailureHandler`. If no failure handler is installed, the default behavior is to attempt to re-create the ServerSocket.
      Parameters:
        `ex` - the exception that occurred during `ServerSocket` creation
      Returns:
        if true, the RMI runtime attempts to retry `ServerSocket` creation
