Configuring security realm throws NullPointerException when operational header allow-resource-service-restart is used

Josef Cacek reports:

Several methods in the SecurityRealmAddHandler class don't handle null value of List<ServiceController<?>> newControllers (c.f. SecurityRealmParentRestartHandler.recreateParentService), and therefor they fail when allow-resource-service-restart==true.

For instance if you run following commands using console:

[standalone@localhost:9999 /] /core-service=management/security-realm=JBossTest:add

{"outcome" => "success"}

[standalone@localhost:9999 /] /core-service=management/security-realm=JBossTest/authentication=local:add(allowed-users="*", default-user="$local")

{allow-resource-service-restart=true}

{
"outcome" => "failed",
"failure-description" => "JBAS014749: Operation handler failed: null",
"rolled-back" => true
}

Throws NPE in the server:
