SN 22.95 verse, our old friend jhāna and upekkha, S&S, all in cohoots

SN 22.95:
B.Sujato trans.

“Pheṇapiṇḍūpamaṃ rūpaṃ,	“Form is like a lump of foam;
vedanā bubbuḷūpamā;	feeling is like a bubble;
Marīcikūpamā saññā,	perception seems like a mirage;
saṅkhārā kadalūpamā;	co-doings like a banana tree;
Māyūpamañca viññāṇaṃ,	and consciousness like a magic trick:
desitādiccabandhunā.	so taught the Kinsman of the Sun.
Yathā yathā nijjhāyati,	However you contemplate them,
yoniso upaparikkhati;	examining them carefully,
Rittakaṃ tucchakaṃ hoti,	they’re void and hollow
yo naṃ passati yoniso.	when you look at them closely.

Here's my more literal translation

“Pheṇa-piṇḍ-ūpamaṃ rūpaṃ,	“(A) Foam-lump-(is)-similar (to) Form;
vedanā bubbuḷ-ūpamā;	experienced-sensations (and a) bubble-(are)-similar;
Marīcik-ūpamā saññā,	(a) mirage-(is)-similar (to) perceptions;
saṅkhārā kadal-ūpamā;	co-doings(and a) banana-tree-(are)-similar;
Māy-ūpamañca viññāṇaṃ,	(a) magic-trick-(is)-similar (to) consciousness:
desitā-dicca-bandhunā.	so taught the Kinsman of the Sun.
Yathā yathā nij-jhāyati,	However however (you use) jhāna (to contemplate them),
yoniso upa-par-ikkhati;	(with) careful equanimous-observation;
Rittakaṃ tucchakaṃ hoti,	they’re void and hollow
yo naṃ passati yoniso.	when you look at them closely.

... and the end of the verse section, we see jhana, S&S, upekkha, viriya,  all operating simulateneously.  avekkheyya is a similar word to upekkha, 

Evaṃ khandhe avekkheyya,	in-such-away (should) aggregates (be)  examined,
bhikkhu āraddha-vīriyo;	(by a) monk (with) aroused-vigor
Divā vā yadi vā rattiṃ,	with lucid-discerning and rememberfulness
sampajāno paṭis-sato.	whether by day or by night.
Jaheyya sabba-saṃyogaṃ,	They should give up all fetters,
kareyya saraṇattano;	and make a refuge for themselves.
Careyy-āditta-sīsova,	Carry-on (as if) raging-fire (on your) head,
patthayaṃ accutaṃ padan”ti.	aspiring to the imperishable state.”

So while you are in jhāna, there are 7 independent jhana factors operating (not 5), with highlighted items mentioned in the verse
