hi to all,

i'm facing up to a class loading issue after i migrated from keycloak 1.5.0 final to keycloak 1.6.1 final.

My application server is jboss WF9.

Specifically i developed my multitenant module following your example.

On Keycloak 1.5.0 adapter i saw that interface 

org.keycloak.adapters.spi.HttpFacade

was in the keycloak-adapter-core dependency while in the 1.6.1  it was moved into keycloak-adapter-spi.

I've referenced these depencencies as provided scoped in my project pom (as showed in the example too):

         <dependency>

<groupId>org.keycloak</groupId>

<artifactId>keycloak-adapter-core</artifactId>

<version>1.6.1.Final</version>

<scope>provided</scope>

</dependency>  

        <dependency>

            <groupId>org.keycloak</groupId>

            <artifactId>keycloak-adapter-spi</artifactId>

            <version>1.6.1.Final</version>

            <scope>provided</scope>

        </dependency>

I have installed the wf9 adapter adding:

<extensions>

    <extension module="org.keycloak.keycloak-adapter-subsystem"/>

        ...

</extensions>

...     

<profile>

    <subsystem xmlns="urn:jboss:domain:keycloak:1.1"/>

    ...

</profile>

and 

<server xmlns="urn:jboss:domain:1.4">

    <subsystem xmlns="urn:jboss:domain:security:1.2">

        <security-domains>

        ...

        <security-domain name="keycloak">

        <authentication>

            <login-module code="org.keycloak.adapters.jboss.KeycloakLoginModule" flag="required"/>

        </authentication>

    </security-domain>

</security-domains>

and eventually by copying the modules folder into the wf9 modules directory.

When i deploy my

org.keycloak.adapters.KeycloakConfigResolver

implementation i get this error:

Why the keycloak-adapter-spi-1.6.1.Final.jar is not loaded by keycloak-adapter-spi module?

If i decide to include the jar inside the myapp.war archive...after deployment i get a Linkage exception error.

What am i doing wrong?

thanks
