RRiBbit is an Open Source Java application framework that eliminates dependencies and simplifies code structure. It can be used as an Eventbus, but improves upon this by being compatible with existing code and allowing bidirectional communication between components. It also supports Remoting, so that you can use Eventbuses that run on other machines, complete with failover, loadbalancing and SSL/TLS support.

There is a newer version: 8.0.0

/**
 * RRB is a convenience class that provides static access to a global {@link RequestResponseBus}. This is ideal for small-scaled Java Applications.
 * 
 * Larger applications will probably want to use a {@link RequestResponseBus} initialized in their Spring Context. Everyone who wants the {@link RequestResponseBus} then has to
 * get it from the Spring Context. Alternatively, you could first initialize the Spring Context and then get the {@link RequestResponseBus} out of it and set it in RRB, if that
 * is convenient for your application.
