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.

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 RMISocketFactory.setFailureHandler. If no failure handler is installed, the default behavior is to attempt to re-create the ServerSocket. 
Params:
ex – the exception that occurred during ServerSocket creation
See Also:
RMISocketFactory.setFailureHandler(RMIFailureHandler)
Returns:
if true, the RMI runtime attempts to retry ServerSocket creation
