Hi all, I'm trying to use the keycloak admin client in JBoss Fuse 6.3.0. Everything works fine when I run the java main class, but when I put this in the JBoss Fuse (with Karaf) I got an error, because the keycloak are using the resteasy, and the OSGI is totally different. So, does anyone knows how to do the same keycloak admin client configuration using this environment? Here is my log: javax.ws.rs.ProcessingException: RESTEASY004655: Unable to invoke request at > org.jboss.resteasy.client.jaxrs.engines.ApacheHttpClient4Engine.invoke(ApacheHttpClient4Engine.java:289)

I'm considering to use another kind of osgi implementation, such as Apache Karaf, eclipse virgo, etc... maybe some of these implementations are not using CXF (I hope so!) Also, I'll take a look in the effort to implement and call the Keycloak REST endpoint with Apache CXF. I'll create JIRA for this!
