org.mule.processor.chain.DefaultMessageProcessorChainBuilder.build()
This builder supports the chaining together of message processors that intercept and also those that don't. While one can iterate over message processor intercepting message processors need to be chained together. One solution is make all message processors intercepting (via adaption) and chain them all together, this results in huge stack traces and recursive calls with adaptor. The alternative is to build the chain in such a way that we iterate when we can and chain where we need to.
We iterate over the list of message processor to be chained together in reverse order collecting up those that can be iterated over in a temporary list, as soon as we have an intercepting message processor we create a DefaultMessageProcessorChain using the temporary list and set it as a listener of the intercepting message processor and then we continue with the algorithm

        // Compose request and response chains. We do this so that if the request
        // chain returns early the response chain is still invoked.
        DefaultMessageProcessorChainBuilder compositeChainBuilder = new EndpointMessageProcessorChainBuilder(endpoint, flowConstruct);
        compositeChainBuilder.setName("OutboundEndpoint '" + endpoint.getEndpointURI().getUri() + "' composite request/response chain");
        compositeChainBuilder.chain(outboundChainBuilder.build(), responseChainBuilder.build());
        return compositeChainBuilder.build();
    }
