Undertow logging failing due to UT000005: getRequestChannel() has already been called

Describe the bug

We have a OncePerRequestFilter that under certain conditions sets the response status and doesn't proceed with filterchain

if (...) {
      response.status = statusCode
} else {
      filterChain.doFilter(request, response)
}

When the condition is met and only status is set then there is no access log entry for that line.

It's failing in ch.qos.logback.core.OutputStreamAppender#subAppend where following RuntimeException is thrown when calling event.prepareForDeferredProcessing():

To Reproduce

Create a OncePerRequestFilter that just sets the status and doesn't call filterChain.doFilter(request, response).

Expected behavior

Should log to the access log.
