In keycloak 17, adding a password blacklist (blacklist.txt) to the password policy i go t an error:
Could not create folder for password blacklists: null/password-blacklists/blacklist.txt
Seems that in version 17 the property jboss.server.data.dir is null and there is no default.
Setting the system property keycloak.password.blacklists.path works fine. Maybe this property should have the default value ‘/opt/keycloak/data’
