Proof step 22 from proof okarray-put-badfield (conclusion)

⊦ okarray(r, ty, st) ∧ fs ' ≠ _type ∧ fs ' ≠ _length → okarray(r, ty, st[r -- fs ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ okarray(r, ty, st) → r ≠ jvmref ∧ r ∈ st
Proof step 21:
okarray(r, ty, st), r ∈ st ⊦ fs ' = _length, fs ' = _type, r = jvmref, okarray(r, ty, st[r -- fs ', val])

Rule argument
