Proof step 23 from proof validstatfield-addclass-same (conclusion)

⊦ validval(str, fis[sk], sk .fs .type, st) ∧ sk ∈ statfields(class) ∧ tdname∃(str, class) ∧ type∃(str, sk .fs .type) ∧ is_fskey(sk) ∧ sk .fs .class = class ∧ sk ∈ fis ∧ class ≠ `java.lang.Object' .class → validstatfield(str, sk, addclass(class, fis, st))

And obtained the following new goals

Proof step 22:
validval(str, fis[sk], sk .fs .type, st), sk ∈ statfields(sk .fs .class), tdname∃(str, sk .fs .class), type∃(str, sk .fs .type), is_fskey(sk), sk ∈ fis ⊦ sk .fs .class = `java.lang.Object' .class, validstatfield(str, sk, addclass(sk .fs .class, fis, st))
