[wildfly-dev] Minor API change

This Elytron pull request [1] introduces a minor API change for users of modifiable security realms who iterate the identities within the realm. This change affects one test in wildfly-core. I have a commit [2] which, if [1] is accepted, I will relay into a pull request for wildfly-core which allows the test to compile and run with both the old and new code. If anyone sees a problem with changing this API, please let me know ASAP.
