Steps to Reproduce:
PREPERATION
# install Apache HTTP server 2.2.22 and config the mod_jk to route servlet request through
ajp:9009
# used the attached standalone.xml
# deploy the attached service.war.
# Install CURL cli utility.
STEPS:
Run the command:
{noformat}
curl -v -X POST --header "Transfer-Encoding: chunked" --header
"Content-Type:appliation/octet-stream"
http://localhost/service-1.0-SNAPSHOT/servlets/ContentSize -d @CURLS.txt
{noformat}
EXPECTED:
{noformat}
Note: Unnecessary use of -X or --request, POST is already inferred.

The curl command will not return until a CTRL-C is issued.
If we append the :8080 to the url, the expected result is returned from server.

ajp connection hangs if a post HTTP request header contains
'Transfer-Encoding: chunked'
-----------------------------------------------------------------------------------------
Key: WFLY-6671
URL: https://issues.jboss.org/browse/WFLY-6671
Project: WildFly
Issue Type: Bug
Components: Web (Undertow)
Affects Versions: 10.0.0.Final
Environment: Apache HTTP server 2.2.22 with mod_jk
Reporter: river shen
Assignee: Stuart Douglas
Attachments: service-1.0-SNAPSHOT.war, src.zip, stacks.txt, standalone.xml,
workers.properties
When upgrading from JBOSS 7 to WILDFLY10, we observed following behavior:
if an HTTP post contains 'Transfer-Encoding: chunked' and
'Content-Type:appliation/octet-stream' in its head, A servlet which handles it
will hang for ever ( until the client drop the connection) if it calls
HttpServletRequest.getInputStream() and tries to read the whole content of the returned
InputStream. The InputStream's read() method will block for ever at the end of the
stream as opposed to return -1.
It only happens when the request is routed by apache web server through ajp; it does not
happen if the client talks to wildfly directly through its 8080 http port.
We have attached a minimal web application that reproduce this issue.
Also attached is the standalone.xml and the apache configuration file.
