Proof step 12 from proof validref-primarray (previous step)

st[r -- _type] = typeval(ty1), st[r -- _length] = intval(i), ty1 = mkarraytype(ty0), ty0 ≤ ty, is_typevalue(st[r -- _type]), r -- _type ∈ st, r -- _length ∈ st, is_arrayref(r, i, st), is_primtype(ty), junkrefs(str, r ' + refs0, mkarraytype(ty0), st), r ∈ st, 0 ≤ i, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ r = jvmref, ty0 = ty

And obtained the following new goals

Proof step 11:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(ty0)), 0 ≤ i, r ∈ st, junkrefs(str, r ' + refs0, mkarraytype(ty0), st), is_primtype(ty), is_arrayref(r, i, st), r -- _length ∈ st, r -- _type ∈ st, ty0 ≤ ty, ∀ j. ¬ j < 0 ∧ ¬ i ≤ j → okval(st[r -- j '], ty) ⊦ ty0 = ty, r = jvmref
