Question: In my test.conf file I have the following configuration

```
akka {
  actor {
    provider = "akka.cluster.ClusterActorRefProvider"

    serializers {
       java = "akka.serialization.JavaSerializer"
    }

    serialization-bindings {
        "java.io.Serializable" = "kyro"
    }
  }
}

```

I am trying to put this configuation in test.properties file as

```
akka.actor.provider=akka.cluster.ClusterActorRefProvider
akka.actor.serializers.java=akka.serialization.JavaSerializer
akka.actor.serialization-bindings."java.io.Serializable" = kryo

```

When I create and AKKA ActorSystem using test.conf file it is working fine but when I am creating an ActorSytem with the test.propeties file as

```
System.setProperty("config.file", "test.properties");
Config config = ConfigFactory.load();
ActorSystem testactor = ActorSystem.create("testactor", config);

```

Here I am getting java ClassNotFoundExcpetion : "java

I seens the way I put the akka.actor.serialization-bindings."java.io.Serializable" in test.properties file is not correct.Please suggest the correct way to put this in .properties file.

Answer: 
It seems a bug in new portal . The save operation doesn't save `isEnabled` to false on server side . Any feedback , you could post to [here](https://feedback.azure.com/forums/169401-azure-active-directory) .

Currently , you could use Azure AD classic portal to modify the app roles in manifest(download the manifest and then upload manifest that changed) . Delete app roles in classic portal works fine in my environment . Please let me know if it helps.
*You cannot delete the assigned roles which are enabled, you first have to set the flag isEnable to false and save the manifest for the roles which you want to delete like this -->`"isEnabled": false` in the manifest and now try to delete the whole appRoles part.*

This is a two-step process but works.
