Proof step 7 from proof fits-put (previous step)

st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r0), sk ∈ instfields(class), is_obj(str, r, st), okarray(r1, byte_type, st), r1 ∈ st ⊦ (st[r1 -- i ', byteval(by)][r -- sk]) = refval(r0), r = jvmref, r1 = jvmref, junkref(str, r, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 6:
⊦ rk ≠ rk0 → (st[rk0, val][rk]) = st[rk]

Rule argument
