Share the same jsessionid in different context root

I have two applications which need a Single Sign On. User once logged into an application should not need login again to another application.
To achieve that I was storing the session id in the cookie. The other application used to retrieve the session and verify the user.
Now, the problem that I am facing, after upgrading to wildfly, is that the each application is producing different jsessionid. I have also tried the workaround mentioned in https://issues.jboss.org/browse/WFLY-3617, but in vain.
I have deployed the same wars in jboss-eap-6.2 and that worked for me.

I have copied the two war over here https://www.dropbox.com/sh/cq5p373wasn5svj/AACyZaBMBCGaNMaBU8zbW82Za?dl=0
