[keycloak-user] TokenService is not visible from class loader

[Pavel Drankov]

Hi,

I'm trying to delete a user during a new user registration process if the
previous account was not confirmed.

And I decided to use Admin REST API with keycloak-admin-client, but, when
using, the following exception is thrown:

16:59:56,028 ERROR [org.jboss.msc.service.fail] (MSC service thread 1-3)

How this error can be fixed?

Best wishes,
