> the benchmarks i added recently for Session#hasPermission show a poor performance of Session#hasPermission compared to regular permission evaluation and jr2.
> i suspect that the most prominent reason for this is the fact that the AccessManager#hasPermission *always* refreshes the underlying permissionprovider even if the session has neither been modified nor refreshed.
