I increased the max-post-size but it didnt work.
standalone.xml :
<subsystem xmlns="urn:jboss:domain:undertow:1.1">
<buffer-cache name="default"/>
<server name="default-server">
<http-listener name="default" socket-binding="http" max-post-size="974247881"/>
<host name="default-host" alias="localhost">
<location name="/" handler="welcome-content"/>
<filter-ref name="server-header"/>
<filter-ref name="x-powered-by-header"/>
</host>
</server>
<servlet-container name="default">
<jsp-config/>
</servlet-container>
<handlers>
<file name="welcome-content" path="${jboss.home.dir}/welcome-content"/>
</handlers>
<filters>
<response-header name="server-header" header-name="Server" header-value="WildFly/8"/>
<response-header name="x-powered-by-header" header-name="X-Powered-By" header-value="Undertow/1"/>
</filters>
</subsystem>
I have found solution for this. I had this same issue and I solved it. It may help others.
For allowing more http request header size you need to change standalone.xml file of jboss or wildfly.
Add max-header-size attribute to default server and restart the server it will work Standalone.conf
<subsystem xmlns="urn:jboss:domain:undertow:1.1">
<buffer-cache name="default"/>
<server name="default-server">
<http-listener name="default" socket-binding="http" max-header-size="974247881"/>
<host name="default-host" alias="localhost">
<location name="/" handler="welcome-content"/>
<filter-ref name="server-header"/>
<filter-ref name="x-powered-by-header"/>
</host>
</server>
...
</subsystem>
