Proof step 13 from proof ac-in-03-02 (previous step)

fs = mkfs(class, ty, fieldvar), r -- sk ∈ addclass(class, (fs ' × val) ' + fis0, st), r ∈ st, ∀ r, sk, class1, st. r -- sk ∈ addclass(class1, fis0, st) ∧ r ∈ st → r = jvmref ∨ r -- sk ∈ st ⊦ r = jvmref, r -- sk ∈ st

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 10:
⊦ addclass(class1, (mkfs(class1, ty, fieldvar) ' × val) ' + fis, st) = (addclass(class1, fis, st)[jvmref -- mkfs(class1, ty, fieldvar) ', val])
Proof step 11:
⊦ r ∈ st → r ∈ addclass(class1, fis, st)
Proof step 12:
r -- sk ∈ addclass(class, fis0, st), r ∈ st, ∀ r, sk, class1, st. r -- sk ∈ addclass(class1, fis0, st) ∧ r ∈ st → r = jvmref ∨ r -- sk ∈ st ⊦ r = jvmref, r -- sk ∈ st
