Proof step 26 from proof okarray-primput (conclusion)

⊦ okprimtype(val, ty) ∧ 0 ≤ j ∧ j < i ∧ okarray(refval(r), ty, i, st) → okarray(refval(r), ty, i, st[r -- j ', val])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 1:
⊦ okarray(refval(r), ty, i, st) → r ≠ jvmref
Proof step 2:
⊦ okarray(refval(r), ty, i, st) → st[r -- _length] .intval = i
Proof step 25:
0 < st[r -- _length] .intval, okprimtype(val, ty), j < st[r -- _length] .intval, okarray(refval(r), ty, st[r -- _length] .intval, st), 0 ≤ j ⊦ r = jvmref, okarray(refval(r), ty, st[r -- _length] .intval, st[r -- j ', val])
