Wildfly Jakarta EE 10 Multipart forms missing

In the process of upgrading from Wildfly 25 to Wildfly 27 (and beyond), we are no longer seeing multipart forms.

The request parts is null (see below at the bottom). So, I'm not sure where it is getting eaten.

Here is the the web.conf

Here is where I want to look at the multipart data.

    @MultipartForm    public void parsePostRequestInputs(HttpServletRequest request, InputValidation validator) throws IOException    {        _filesToUpload = new HashMap<String, Part>();        if (request.getContentType().contains("urlencoded"))        {            //            // read the request            //            Map<String, String[]> params = request.getParameterMap();            _entries = new String[params.keySet().size()];            int pos = 0;            for (String param : params.keySet()) {               _entries[pos] = param +"=" + URLDecoder.decode(params.get(param)[0], StandardCharsets.UTF_8);               pos++;            }        }        else        {            _log.debug("Checking for multipart.");            try {                request.getParts();            } catch (Exception e) {                _entries = new String[0];                return;            }            try            {                final Collection<Part> parts = request.getParts();                List<String> temp = new ArrayList<String>();                for (final Part part : parts)                {                    String fileItemFieldName = part.getSubmittedFileName();                    if (!(fileItemFieldName.startsWith("fileUpload")))                    {                        temp.add(part.getName() +"=" + fileItemFieldName);                    }                    else                    {                        String index = part.getName().substring(10);                        _filesToUpload.put(index, part);                        String fileItemName = part.getName();                        if (fileItemName.length() > 30)                        {                            fileItemName = fileItemName.substring(0, 30);                        }                        temp.add("uploadPixName" + index +"=" + fileItemName);                    }                }                _entries = temp.toArray(new String[temp.size()]);            }            catch (FileUploadException | ServletException e)            {                _log.error("There was an issue uploading files for the POST request. " + e);            }        }    }

The request looks like this in the debugger:

request = {HttpServletRequestImpl@16372} "HttpServletRequestImpl [ POST /esg/client ]" exchange = {HttpServerExchange@16383} "HttpServerExchange{ POST /esg/client}" originalServletContext = {ServletContextImpl@16384}  servletContext = {ServletContextImpl@16384}  attributes = null servletInputStream = null reader = null cookies = null parts = null asyncStarted = false asyncContext = null queryParameters = null parsedFormData = null formParsingException = null characterEncoding = null readStarted = false sessionCookieSource = null

This happens for all of our multipart data requests. This is perhaps the simplest request. If we use get with URL encodings, everything works fine. Any ideas where the multipart data has gone?

TIA!
