[keycloak-user] Java API documentation

Fri Oct 31 11:59:24 EDT 2014

I have upgraded to 1.0.4.Final but still have the issue.

I would consider this as a bug in Keycloak -well in the client at least- as
am using Wildfly and i am embedding the Jackson dependencies with my war
anyway. These dependencies are pulled by the Keycloak ones.

@Keycloak team : should i open an issue for this one ?
