Is it necessory to attain higher Jhana to experience Nibbana?

Can some one experience nibbana just being in 1st Jhana. or 2nd..or 3rd..? I read in one of sutta that to be arhant even 1st Jhana is sufficient. But when someone becomes sotapanna, or higher Arya by just practicing 1st Jhana.then technically what happes? (1) **Either unknowingly and quickly he goes through** 2,3,4,5,6,7,8, Jhana and then 9th. (2) **or he jumps** 2,3,4,5,6,7,8 and directly expirience 9th (Nibbana)
