Proof step 24 from proof isobj-addobj-04 (previous step)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 23:
fis .keys = instfields(class), mkfs(class0, ty, fieldvar) ' ∈ fis, validfieldinits(fis, st), mkfs(class0, ty, fieldvar) ' ∈ instfields(class) ⊦ r = jvmref, okval(fis[mkfs(class0, ty, fieldvar) '], ty)

Rule argument
