Proof step 46 from proof validstatfields-put-statfield-06 (conclusion)

⊦ ¬ sk ∈ statfields(class) ∧ ( ¬ is_fskey(sk) ∨ sk .fs .type ≠ void_type ∨ sk .fs ≠ mkfs(`java.lang.Object' .class, void_type, `uninit' .field) ∧ sk .fs ≠ mkfs(class, void_type, `initstate' .field)) → (validstatfields(str, statfields(class), st[jvmref -- sk, val]) ↔ validstatfields(str, statfields(class), st))

And obtained the following new goals

Proof step 45:
is_indexkey(sk) ∨ sk .fs .type ≠ void_type ∨ sk .fs ≠ mkfs(`java.lang.Object' .class, void_type, `uninit' .field) ∧ sk .fs ≠ mkfs(class, void_type, `initstate' .field) ⊦ validstatfields(str, statfields(class), st[jvmref -- sk, val]) ↔ validstatfields(str, statfields(class), st), sk ∈ statfields(class)
