Proof step 21 from proof getbytearray-pseq (previous step)

validref(`docs2store', r, mkarraytype(byte_type), st) ∧ ps=(r, st, r1, st1) ∧ 0 ≤ 0 ∧ 0 < st[r -- _length] .intval ∧ 0 + st1[r1 -- _length] .intval ≤ st[r -- _length] .intval ∧ 0 ≤ st1[r1 -- _length] .intval ∧ r ≠ jvmref → getbytearray(r, 0, st1[r1 -- _length] .intval, st) = getbytearray(r1, 0, st1[r1 -- _length] .intval, st1), validref(`docs2store', r, mkarraytype(byte_type), st), ps=(r, st, r1, st1) ⊦ r = jvmref, getbytearray(r, 0, st[r -- _length] .intval, st) = getbytearray(r1, 0, st1[r1 -- _length] .intval, st1)

Proof step 20:
validref(`docs2store', r, mkarraytype(byte_type), st), ps=(r, st, r1, st1), ¬ st[r -- _length] .intval ≤ 0 ∧ ¬ st[r -- _length] .intval < st1[r1 -- _length] .intval ∧ ¬ st1[r1 -- _length] .intval < 0 → getbytearray(r, 0, st1[r1 -- _length] .intval, st) = getbytearray(r1, 0, st1[r1 -- _length] .intval, st1) ⊦ r = jvmref, getbytearray(r, 0, st[r -- _length] .intval, st) = getbytearray(r1, 0, st1[r1 -- _length] .intval, st1)
