Proof step 6 from proof isobj-put-03 (previous step)

st[r -- _type] = typeval(mkclasstype(class0)), r ∈ st, r -- _type ∈ st, okval(val, ty), mkfs(class1, ty0, fieldvar0) ' ∈ instfields(class0), r -- mkfs(class1, ty0, fieldvar0) ' ∈ st, okval(st[r -- mkfs(class1, ty0, fieldvar0) '], ty0) ⊦ r = jvmref, ty = void_type, okval(st[r1 -- mkfs(class, ty, fieldvar) ', val][r -- mkfs(class1, ty0, fieldvar0) '], ty0)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 5:
⊦ rk ≠ rk0 → (st[rk0, val][rk]) = st[rk]

Rule argument
