I have almost exactly the same problem:
I run the keycloak server in a wildfly 14 distribution. When I try to get a token from a
call within a deployed webapp (same wildfly) I get the same NPE. When running exactly the
same code from an external application all runs fine, no NPE.
I suppose running the code from within a war/ear file does not exactly the same like
running the code from single class. It worked versions ago (keycloak 2.1). For know I
don't have an idea what's the difference ...

Trying this code I receive a null token:
Keycloak keycloak =
Keycloak.getInstance("http://localhost:8180/auth",<http://localhost:8180/auth%22,>
"master", "admin", "admin", "admin-cli");
keycloak.tokenManager().getAccessTokenString();
