Proof step 12 from proof validrefs-applast-array-null (previous step)

And obtained the following new goals

Proof step 11:
st[r -- _type] = typeval(mkarraytype(ty0)), type∃(str, ty0), validrefs(str, refs + r ', ty, st), r ∈ st, 0 < st[r -- _length] .intval, 0 ≤ i, is_reftype(ty0), i < st[r -- _length] .intval, r -- _type ∈ st, okarray(r, ty0, st) ⊦ r = jvmref, ty0 .jtelemtype = void_type, ty0 .jtelemtype = abstract_type, is_referencevalue(st[r -- i ']), validrefs(str, refs + r ' + jvmref ', ty, st)
