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:
