Multipart form-data larger than 16KiB is not available through Servlet getParameter API after JBoss EAP 7.4.12

Issue

• The POST request data larger than 16KiB in multipart/form-data request becomes unavailable through Servlet getParameter API after JBoss EAP 7.4.12
• When submitting field values via enctype multipart/form-data undertow makes up a submittedFilename for values larger than 16383 Bytes. This leads application to confuse the values with file uploads. Especially JSF wont invoke the bean setter for such values.
