Hello cloakees. I'm having an interesting problem while using the admin-client from 1.9.1. Initially, things go well. I can extract data as expected. However, after a couple of minutes (I think when the admin-client-token needs refreshing), I'm suddenly getting errors: "java.lang.IllegalArgumentException: interface org.keycloak.admin.client.token.TokenService is not visible from class loader" I added a full stacktrace below. I find it odd that some functionality does work, but other does not. What's causing this? keycloak-admin-client-1.9.1.Final.jar is on the classpath, which is where that interface appears to live.

I do have core on my classpath. I am bound to a setup where keycloak is instantiated by a classloader that is a child of the classloader that triggers the requests. Is that a problem? It obviously isn't a problem for some calls, but perhaps that there's something different with that TokenService? I'm having trouble determining the exact set of dependencies that I need for my project. Is that documented somewhere? Does anyone know how I could further diagnose this issue?
