[keycloak-user] Exception loading Keycloak modules in Wildfly 9.0

[Vijay Bhadriraju]

I am getting the following exception after unzipping the 
keycloak-wildfly-adapter-dist-1.1.0.Final.zip into the WildFly 9.0 server 
and configuring the standalone.xml file with the following lines as 
described in the keycloak documentation. I have tried this with Wildfly 
10.0 version also and get the same error.

<server xmlns="urn:jboss:domain:1.4">
<extensions>
<extension module="org.keycloak.keycloak-adapter-subsystem"/>
...
</extensions>
<profile>
<subsystem xmlns="urn:jboss:domain:keycloak:1.1"/>
...
</profile>

How do I resolve this keycloak module loading exception?
