Proof step 36 from proof exactarray-copy-01 (previous step)

exactarray(r, byte_type, st), exactarray(r0, byte_type, st), i + j ≤ st[r0 -- _length] .intval, r ∈ st, r0 ∈ st, 0 ≤ i, 0 ≤ j ⊦ r = jvmref, r0 = jvmref, exactreftype(refval(r), mkarraytype(byte_type), arraycopy(r0, i, r, i0, j, st)) ∧ r ≠ jvmref ∧ r -- _length ∈ arraycopy(r0, i, r, i0, j, st) ∧ is_integervalue(arraycopy(r0, i, r, i0, j, st)[r -- _length]) ∧ 0 ≤ (arraycopy(r0, i, r, i0, j, st)[r -- _length]) .intval ∧ is_arrayref(r, (arraycopy(r0, i, r, i0, j, st)[r -- _length]) .intval, arraycopy(r0, i, r, i0, j, st))

And obtained the following new goals

Proof step 3:
⊦ exactarray(r, ty, st) → ¬ st[r -- _length] .intval < 0
Proof step 35:
exactarray(r, byte_type, st), exactarray(r0, byte_type, st), i + j ≤ st[r0 -- _length] .intval, r ∈ st, r0 ∈ st, 0 ≤ i, 0 ≤ j ⊦ r = jvmref, r0 = jvmref, exactreftype(refval(r), mkarraytype(byte_type), arraycopy(r0, i, r, i0, j, st)) ∧ r -- _length ∈ st ∧ is_integervalue(st[r -- _length]) ∧ is_arrayref(r, st[r -- _length] .intval, arraycopy(r0, i, r, i0, j, st))
