Proof step 15 from proof ac-in-03-02 (previous step)

sk0 = fs ', is_fskey(sk0), r ∈ st, r -- sk ∈ addclass(fs .class, (sk0 × val) ' + fis0, 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 9:
⊦ r ∈ st → r ∈ addclass(class1, fis, st)
Proof step 14:
r -- sk ∈ addclass(fs .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
