* Implementations must also implement {@link Supplier Supplier<EndpointServlet>}
* and return a valid {@link EndpointServlet}.

* This annotation can be used when existing servlets need to be exposed as actuator
* endpoints, but it is at the expense of portability. Most users should prefer the
* {@link Endpoint @Endpoint} or {@link WebEndpoint @WebEndpoint} annotations whenever
* possible.
