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?

Guus

The stacktrace hides whether this is ClassNotFoundException or
NoClassDefFoundError, so it's possible that TokenService is actually
visible, but not one of its dependencies.
You'll definitely also need to add keycloak-core.jar to your classpath.
