And obtained the following new goals

Proof step 74:
st[r -- sk] = refval(r0), fits(r0, sks0, st), is_referencevalue(st[r -- sk]), r1 ∈ st, okarray(r1, byte_type, st), ∀ r, st, r1, i, by, str. fits(r, sks0, st) ∧ okarray(r1, byte_type, st) ∧ r1 ∈ st → (st[r1 -- i ', byteval(by)][r -- sks0]) = st[r -- sks0] ∨ r1 = jvmref ∨ junkref(str, r, st), is_arraytype(st[r -- _type] .type) → is_indexkey(sk) ∧ 0 ≤ sk .index ∧ sk .index < st[r -- _length] .intval, is_classtype(st[r -- _type] .type) → sk ∈ instfields(st[r -- _type] .type .class) ⊦ r = jvmref, (st[r1 -- i ', byteval(by)][r -- (sk ' + sks0)]) = st[r -- (sk ' + sks0)], r1 = jvmref, junkref(str, r, st)
