Proof step 13 from proof validstatfields-put-statfield-02 (conclusion)

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

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ is_indexkey(sk) → ¬ validstatfield(str, sk, st)
Proof step 12:
validstatfield(str, sk, st[jvmref -- sk, val]), validstatfields(str, sks, st), is_fskey(sk), sk .fs .field ≠ `initstate' .field ∧ sk .fs ≠ mkfs(`java.lang.Object' .class, void_type, `uninit' .field) ∨ sk .fs .type ≠ void_type ⊦ validstatfields(str, sks, st[jvmref -- sk, val])
