So I set a conditional breakpoint for response.isCommitted() all the way
down in CoyoteAdapter.service() (called by Http11Processor.process())
and the response was committed at that point when this happened. Here is
the source where the breakpoint was:

            // Parse and set Catalina and configuration specific 
            // request parameters
            if ( postParseRequest(req, request, res, response) ) {
                // Calling the container

// BREAKPOINT IS HERE
connector.getContainer().getPipeline().getFirst().invoke(request,
response);
            }

I'm going to try to go ever further down and see if there is a point at
which it isn't committed.
