Proof step 22 from proof exactarray-put-02 (previous step)

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

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 21:
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)])
