Proof step 21 from proof exactarray-put-02 (previous step)

val = refval(r) ∧ is_referencevalue(val), exactarray(val, byte_type, i, st) ⊦ r = jvmref, is_arrayref(r, i, st[r0 -- j ', byteval(by)]) ∧ st[r -- _length] = intval(i) ∧ r -- _length ∈ st ∧ exactreftype(val, mkarraytype(byte_type), st[r0 -- j ', byteval(by)])

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 3:
⊦ exactarray(refval(r), ty, i, st) → r ≠ jvmref
Proof step 4:
⊦ exactarray(refval(r), ty, i, st) → st[r -- _length] .intval = i
Proof step 20:
exactarray(refval(r), byte_type, st[r -- _length] .intval, st) ⊦ r = jvmref, is_arrayref(r, st[r -- _length] .intval, st[r0 -- j ', byteval(by)]) ∧ st[r -- _length] = intval(st[r -- _length] .intval) ∧ r -- _length ∈ st ∧ exactreftype(refval(r), mkarraytype(byte_type), st[r0 -- j ', byteval(by)])
