FYI, I am doing the async processing on the Container thread itself, just that I yield the thread back if I can't read without blocking.
Based on the code here <https://github.com/apache/tomcat/blob/main/java/org/apache/coyote/AbstractProcessor.java#L121-L122>, I see that the error is only dispatched if the request is not being executed in the container thread.
