Proof step 9 from proof okarray-getbar-len (previous step)

st[val .refval -- _length] .intval = n→i(n), okarray(val .refval, byte_type, st), val .refval ∈ st ⊦ # getbytearray(val .refval, st) = n, val .refval = jvmref

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 8:
val = refval(r) ∧ is_referencevalue(val), st[r -- _length] .intval = n→i(n), okarray(r, byte_type, st), r ∈ st ⊦ # getbytearray(r, st) = n, r = jvmref
