Hostile mobs generally despawn in Peaceful. Anyways, this bug effects all shulkers, both from spawn eggs and naturally generated (even if the chunks were generated in Peaceful)
Confirmed for 15w31c.
Confirmed for 15w32a and 15w32b.

This issues section has been fixed in 15w40a
Not for me.
edit: They don't despawn, but apparently no longer attack. Updating the ticket accordingly.
15w40b - confirmd
WAI per Searge from MC-91436:
Shulker will not despawn in peaceful mode, but they are not attacking anymore
Resolving to MC-91436 because it has a dev comment.
Hostile mobs attack when force spawned in peaceful. However, shulkers probably shouldn't spawn in peaceful.
