Proof step 9 from proof byteval (previous step)

¬ is_bytevalue(st[r -- (i + i0) ']), i0 ≤ j, i + j < st[r -- _length] .intval, okarray(r, byte_type, st), 0 ≤ i + i0, r ∈ st ⊦ byteval(st[r -- (i + i0) '] .byteval) = st[r -- (i + i0) '], r = jvmref

And obtained the following new goals

Proof step 8:
r ∈ st, 0 ≤ i + i0, okarray(r, byte_type, st), i + j < st[r -- _length] .intval, i0 ≤ j ⊦ r = jvmref, byteval(st[r -- (i + i0) '] .byteval) = st[r -- (i + i0) '], is_bytevalue(st[r -- (i + i0) '])
