[keycloak-dev] keycloak/resteasy problem

[Stan Silvert]

I'm trying to call the keycloak rest API using the keycloak admin 
client.  The call works fine from a web app but when I try to do the 
same thing from the keycloak subsystem I get this:

14:01:51,918 ERROR [org.jboss.msc.service.fail] (MSC service thread
