Proof step 26 from proof isobj-addobj-04 (previous step)

sk .fs = mkfs(class0, ty, fieldvar), fis .keys = instfields(class), sk ∈ fis, validfieldinits(fis, st), sk ∈ instfields(class) ⊦ is_indexkey(sk), r = jvmref, ¬ is_indexkey(sk) ∧ okval(fis[sk], ty)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 25:
