And obtained the following new goals

Proof step 37:
st[r1 -- _length] = intval(i0), st[r1 -- i '] = refval(r0), i < i0, okreftype(refval(r1), mkarraytype(byte_type), st), r1 -- _length ∈ st, is_integervalue(st[r1 -- _length]), is_arrayref(r1, i0, st), 0 ≤ i, 0 < i0, r1 ∈ st, 0 ≤ i0, ∀ j. ¬ j < 0 ∧ ¬ i0 ≤ j → is_bytevalue(st[r1 -- j ']) ⊦ r1 = jvmref, junkref(str, r1, st)
