I have to agree with Fomsie. Spring Attack negates the normal trigger effect of movement vs the target. The target isn't opting to not make an attack, they are denied the opportunity.
No trigger. No effect.
Same with the need for an acrobatics check. No trigger, no effect. At least from the target of the Spring Attack. This would be a case of feats trumping general rules (as is the norm).
However - as a GM, I generally allow Acrobatics checks as part of the movement effect of Spring Attack. Yes, Spring Attack IS a full round action, but movement is required (basically, a move with specific requirements and limitations, and a standard attack, also with limitations), but I would allow acrobatics from any other foe whose path is crossed.
Does it help against the target? No, because that person never provoked. However, that could lead to some AoO bonuses, if strategically used...
