public class BulkheadMethodInterceptor
extends AbstractMethodInterceptor
A MethodInterceptor to handle all methods annotated with Bulkhead. It will handle methods that return a Promise, Flux, Mono, CompletionStage, or value.

Given a method like this: 


     @Bulkhead(name = "myService")
     public String fancyName(String name) {
         return "Sir Captain " + name;
     }
each time the #fancyName(String) method is invoked, the method's execution will pass through a a Bulkhead (concurrent limiting) according to the given policy.

The fallbackMethod parameter signature must match either:

1) The method parameter signature on the annotated method or 2) The method parameter signature with a matching exception type as the last parameter on the annotated method

The return value can be a Promise, CompletionStage, Flux, Mono, or an object value. Other reactive types are not supported.

If the return value is one of the reactive types listed above, it must match the return value type of the annotated method.
