-----------------------------
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.

> 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.
