[keycloak-user] Get the realms through the Client Admin Api

[Felix Knecht]

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 ...
