Proof step 30 from proof validstatfield-addclass-other (conclusion)

⊦ is_fskey(sk) ∧ sk .fs .class ≠ class ∧ class ≠ `java.lang.Object' .class → (validstatfield(str, sk, addclass(class, fis, st)) ↔ validstatfield(str, sk, st))

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 29:
is_fskey(sk) ⊦ sk .fs .class = class, class = `java.lang.Object' .class, validstatfield(str, sk, addclass(class, fis, st)) ↔ validstatfield(str, sk, st)

Rule argument
