Hi Stian, thank you for following up.

To keep things simple the application is working on the full KC 1.5.0.Final.zip distribution but not on the 1.9.0.Final.zip distribution.  My war file is secured by KC and has the keycloak.json file updated when I attempt to use the 1.9 distribution.

I do use the admin client and the representation classes to retrieve data from the server which all works fine in 1.5.0.

Here are further details from my POM file.
<jackson.version>2.5.4</jackson.version>
<resteasy.version>3.0.14.Final</resteasy.version>
<deltaspike.version>1.5.0</deltaspike.version>

Do you have the Keycloak adapter subsystem installed? Is your WAR secured by Keycloak? If so it should have the required dependencies with the exception of the admin client. If no to those questions you need to add a dependency to keycloak-core.

Hi all,

I have an Java EE7 application using KC on wildfly and I'm porting it over to work on KC 1.9.0.Final and Wildfly 10.  The issue I'm running into has the following stack trace:

My UserAsyncManager class is just a SLSB with an @Asynchronous method to take the KC UserRepresentation and save it to my application database for further usage.  I am using the Keycloak-admin-client in my application to retrieve the user representation from the KC server.

I've been struggling to find a solution to this problem for a few days and need some help from the community.  The relevant POM dependency versions are the following:
<jackson.version>2.5.4</jackson.version>
<resteasy.version>3.0.14.Final</resteasy.version>
<deltaspike.version>1.5.0</deltaspike.version>
<keycloak.version>1.9.0.Final</keycloak.version>
I can include the full POM if needed.

Any thoughts?

Thanks,
Jeff
