Proof step 3 from proof ac-in-07 (conclusion)

class1 ≠ class2 ⊦ (jvmref -- mkfs(class1, ty, fieldvar) ') × val ∈ addclass(class2, fis, st) ↔ (jvmref -- mkfs(class1, ty, fieldvar) ') × val ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
class1 ≠ class2 ⊦ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ addclass(class2, fis, st) ↔ jvmref -- mkfs(class1, ty, fieldvar) ' ∈ st
Proof step 2:
class1 ≠ class2 ⊦ (addclass(class2, fis, st)[jvmref -- mkfs(class1, ty, fieldvar) ']) = st[jvmref -- mkfs(class1, ty, fieldvar) ']

Rule argument
