Please add the information to chapter "2.1.3.10. Securing the Hawtio Administration Console" (first step) that the configuration of $FUSE_HOME/etc/system.properties should changed when Fuse is JBoss Fuse 6.3.0 Rollup 5 is used. The reason for this change is that Fuse changed keycloakClientConfig file to URL and it doesn't accept file path. This should be fixed in Rollup 6. URL and also filepath will be accepted.

the config change from:

hawtio.keycloakClientConfig=${karaf.base}/etc/keycloak-hawtio-client.json

to:

hawtio.keycloakClientConfig=file://${karaf.base}/etc/keycloak-hawtio-client.json
