[keycloak-user] NullPointerException when attempting to remove group

[Marek Posolda]

Could you try if you can delete group in your environment with the fresh 
realm without LDAP? If it doesn't work for you just with LDAP, it's 
likely a bug. Feel free to create JIRA with steps to reproduce.

Thanks,
Marek
