-----------------------------------------------------------------

Ideally, from a user's perspective, I would expect CamelContext to allow a direct put into its registry. Something like: getContext().getRegistry().add("thisand", "that");. But given the number of different registry combinations that is probably not very easy to implement in a clean fashion.

Of course there is the usual way of passing the registry reference to the routebuilders, but that is not very straightforward when working with org.apache.camel.main.Main.

Ideally, from a user's perspective, I would expect CamelContext to allow a direct put into its registry. Something like: getContext().getRegistry().add("thisand", "that");. But given the number of different registry combinations that is probably not very easy to implement in a clean fashion.

And of course there is the usual way of passing the (simple)registry reference to the extended routebuilders. In the above self-referencing method we have to do casting, which makes me feel unsure about it.

> I haven't found a nice way to add beans to Camel context registry through Camel context reference in plain Java. Some beans are only needed by a certain endpoint and it would make sense to set the bean up with the endpoint in routebuilder configure method.
> If we added a reference to self in SimpleRegistry we could setup the Camel context by DefaultCamelContext(new SimpleRegistry()) or OsgiDefaultCamelContext(bundleContext, new SimpleRegistry()) and easily access the registry from the routebuilder with SimpleRegistry registry = (SimpleRegistry) getContext().lookupByName(SimpleRegistry.NAME);.
> Then we can set up beans in routebuilder configure and simply add them with registry.put. And the same routebuilder could be used in plain Java, in OSGi or elsewhere.
> All that is needed is this change in SimpleRegistry:
> {code}
> public static final String NAME;
> static {
>    NAME = java.util.UUID.randomUUID().tostring();
> }
> public SimpleRegistry() {
>    put.(NAME, this);
> }
> {code}
