Proof step 7 from proof exactarray-02-01 (previous step)

st[r -- _type] = typeval(ty0), ty0 = mkarraytype(ty), st[r -- _length] = intval(i), r -- _type ∈ st, is_typevalue(st[r -- _type]), r -- _length ∈ st, is_arrayref(r, i, st), r ∈ st ⊦ r = r0, r = jvmref, is_classtype(ty), is_arraytype(ty), exactreftype(refval(r), mkarraytype(ty), st)

And obtained the following new goals

Proof step 6:
st[r -- _length] = intval(i), st[r -- _type] = typeval(mkarraytype(ty)), r ∈ st, is_arrayref(r, i, st), r -- _length ∈ st, r -- _type ∈ st ⊦ r = jvmref, r = r0, exactreftype(refval(r), mkarraytype(ty), st), is_arraytype(ty), is_classtype(ty)
