I have been seeing this a bit recently (I'm using KeyCloak 1.2.0). I
haven't tracked down a reproducible test case yet, but I'm wondering if
there are situations where Tomcat will attempt to stop the value before it
is started, which leads to nodesRegistrationManagement being null.
Maybe it is worth adding a null check in
AbstractKeycloakAuthenticatorValve.beforeStop()?
