Hi,
Thanks for continuing looking at this. Let's do this, I'll do the same
steps using Jetty to reproduce the issue, will let you know during this
week once I have something to share.
Another weird thing is that the example actually should return all
permissions and make them available after the login. Will check how this is
working with Jetty too. The tests we have in the quickstarts are
wildfly based ....
