  * <p>
  * In the case of an error condition response, the <code>Throwable</code> passed to the <code>onError</code> consumer
  * <i>should</i> be a WebApplicationException containing the invalid <code>Response</code> object.
+ * <p>
+ * Note that if, for any of the registered event consumers, an invocation of {@link Consumer#accept(Object)
+ * Consumer&lt;InboundSseEvent&gt;#accept(InboundSseEvent)} method throws an exception, this is not an error condition.
+ * Thus <code>onError</code> is not invoked and event processing is not stopped.
+ * Users are encouraged to handle exceptions on their own as part of the event processing logic.
