Proof step 20 from proof isarray-addarray-01 (previous step)

st[r1 -- _type] = typeval(mkarraytype(ty0)), okarray(r1, ty0, addarray(r0, ty, vals, st)), r1 -- _type ∈ st, r1 ∈ st ⊦ r1 = jvmref, r1 = r0, r1 ≠ jvmref ∧ r1 -- _type ∈ st ∧ is_typevalue(st[r1 -- _type]) ∧ is_arraytype(st[r1 -- _type] .type) ∧ okarray(r1, st[r1 -- _type] .type .type, st)

Proof step 19:
st[r1 -- _type] = typeval(mkarraytype(ty0)), r1 ∈ st, r1 -- _type ∈ st, okarray(r1, ty0, addarray(r0, ty, vals, st)) ⊦ r1 = r0, r1 = jvmref, okarray(r1, ty0, st)
