inconsistent behavior of HttpServletRequest.getUserPrincipal() between EAP6 and EAP7

Solution In Progress - Updated -

Issue

The behavior of HttpServletRequest.getUserPrincipal() in EAP7 is different from EAP6. You can see it deploying the attached test.war in both of EAP6 and EAP7 as follows:

$ $JBOSS_HOME/bin/jboss-cli.sh -c --file=add_security-domain.cli
$ cp test.war $JBOSS_HOME/standalone/deployments/

Then restart EAP6/7, and you will see the behavior:

  1. Access http://localhost:8080/test/ . You will see HttpServletRequest.getUserPrincipal() is null in both EAP
  2. Access http://localhost:8080/test/secure/, and login as test/test. Then, you will see HttpServletRequest.getUserPrincipal() is "test" in both EAP
  3. Access http://localhost:8080/test/ again. You will see HttpServletRequest.getUserPrincipal() is "test" in EAP6, but HttpServletRequest.getUserPrincipal() is null in EAP7.
