[keycloak-user] Not before policy in accesstoken uses dash-separator (in json), why?

[Jakob Thun]

Hello Keycloak gurus,

Quick simple question out of curiosity.

Since all other AccessToken fields use a underscore_separator, why is the
not-before-policy with dashes.

See:
https://github.com/keycloak/keycloak/blob/3.1.x/core/src/main/java/org/keycloak/representations/AccessTokenResponse.java

Anyone have a clue?

Regards
Jakob
