Proof step 6 from proof compatarray-void (previous step)

And obtained the following new goals

Proof step 5:
st[r0 -- _type] = typeval(ty), st[r -- _length] = intval(i0), st[r -- _type] .type = mkarraytype(void_type), st[r -- i '] = refval(r0), r0 ∈ st, is_subtype(str, ty, void_type), is_reftype(ty), is_typevalue(st[r0 -- _type]), r0 -- _type ∈ st, r ∈ st, 0 ≤ i, is_arrayref(r, i0, st), r -- _length ∈ st, i < i0, 0 ≤ i0, 0 < i0, is_classtype(ty) → class+∃(str, ty .class), has_classtype(ty) → tdname+∃(str, ty .jtelemtype .class) ⊦ r = jvmref, r0 = jvmref
