> Project: Cassandra
> Issue Type: Bug
> Reporter: Jacek Lewandowski
> Priority: Normal
>
> CIDR permission cache code:
> {code:java}
> /**
> * Invalidate a role from CIDR permissions cache
> * @param roleName role for which to invalidate the cache
> * @return boolean returns true if given role found in the cache and
> invalidated, otherwise returns false
> */
> public boolean invalidateCidrPermissions(String roleName)
> {
> if (cache.getIfPresent(roleName) == null)
> return false;
> invalidate(RoleResource.role(roleName));
> return true;
> }
> {code}
> passes {{String}} role name to the cache and if it returns {{null}} it just
> returns {{false}}. It will always return {{null}} because cache expects
> objects of type {{RoleResource}}.
