Proof step 44 from proof validstatfields-put-statfield-06 (previous step)

sk .fs = mkfs(class0, ty, fieldvar), is_indexkey(sk) ∨ ty ≠ 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)

Proof step 43:
sk .fs = mkfs(class0, ty, fieldvar), is_indexkey(sk) ∨ ty ≠ void_type ∨ (class0 ≠ `java.lang.Object' .class ∨ fieldvar ≠ `uninit' .field) ∧ (class0 ≠ class ∨ fieldvar ≠ `initstate' .field) ⊦ validstatfields(str, statfields(class), st[jvmref -- sk, val]) ↔ validstatfields(str, statfields(class), st), sk ∈ statfields(class)
