Matti Bickel commented on RF-13444:
-----------------------------------
I've spent an afternoon debugging this, using Wildfly-8.0.0.CR1
(undertow-core-1.0.0.Beta30, JSF 2.2.4) with RF-4.3.4 and summarized what I
learned at
http://stackoverflow.com/a/21157340/785663
Short version: the MultipartRequest25 that RF-4.3 (and looking at the code,
RF-5, too) uses tries to parse the request body again if a parameter could not
be found (returned null). Since the servlet container already mangled the body,
you get an EOF from the stream and the code converts this into the IOException
seen here.
A possible remedy probably involves creating a MultipartRequest30 that is
written with Servlet-3.0 containers in mind?
