[keycloak-user] Get the realms through the Client Admin Api

[Luca Stancapiano]

I'm triing a simple call via Rest to my keycloak 4.7.0.Final server distribution. I created an admin user through the admin web console:

user: admin
pass: admin

The server works on the 8180 port and it starts through the command:

./standalone.sh -Djboss.socket.binding.port-offset=100

I try to do a simple call using the admin client api imported through the dependency in the pom:

<dependencies>
    <dependency>
	<groupId>org.keycloak</groupId>
	<artifactId>keycloak-admin-client</artifactId>
	<version>4.7.0.Final</version>
	<scope>test</scope>
    </dependency>
</dependencies>

Here the java code:

Keycloak keycloak = Keycloak.getInstance("http://localhost:8180/auth", "master", "admin", "admin", "admin-cli");
keycloak.realm("master").clients().findAll();

when the findAll method is executed I receive the Exception:
