JBoss EAP 6: Request header is too large

If, when testing a Java application on a JBoss EAP 6 Server, a message like the following appears:

12:12:27,174 DEBUG [org.apache.coyote.http11] (http-127.0.0.1:8080-3) JBWEB003070: Error parsing HTTP request header: java.lang.IllegalArgumentException: JBWEB002015: Request header is too large

It is because the size of the request we send is much larger than the allowed size, than by default of 8 KB.
To solve this message, simply add the following property to either the standalone.xml or domain.xml file in which we will increase the maximum allowed of the request to 64 KB:
&amp;amp;amp;amp;lt;property name="org.apache.coyote.http11.Http11Protocol.MAX_HEADER_SIZE" value="65536"/&amp;amp;amp;amp;gt;


Then we restart the server and test the application again.
We will see that the message has disappeared and that our application works normally!
