Proof step 12 from proof okarray-init-07 (previous step)

newref(r, st), ∃ n. n < # vals ∧ vals[n] = val, ∀ j. ¬ j < 0 ∧ ¬ n→i(# vals) ≤ j → is_bytevalue(addarray(r, byte_type, vals, st)[r -- j ']) ⊦ r = jvmref, is_bytevalue(val)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 11:
