Proof step 18 from proof addbar-okarray-01 (previous step)

⊦ r = jvmref, is_arrayref(r, n→i(# ints), addarray(r, byte_type, mkjavavalues(is2bs(ints)), st)) ∧ (0 ≤ j ∧ j < n→i(# ints) → is_bytevalue(addarray(r, byte_type, mkjavavalues(is2bs(ints)), st)[r -- j ']))

User applied rule case distinction

And obtained the following new goals

Proof step 8:
⊦ is_arrayref(r, n→i(# ints), addarray(r, byte_type, mkjavavalues(is2bs(ints)), st)), r = jvmref
Proof step 17:
⊦ 0 ≤ j ∧ j < n→i(# ints) → is_bytevalue(addarray(r, byte_type, mkjavavalues(is2bs(ints)), st)[r -- j ']), r = jvmref
