And obtained the following new goals

Proof step 31:
is_primtype(ty), okarray(r, ty, st), r ∈ st, is_array(r, st), ¬ st[r -- _type] .type ≤ mkarraytype(ty) ∨ st[r -- _type] .type .jtelemtype = abstract_type ∨ st[r -- _type] .type .jtelemtype = void_type ∨ ¬ type∃(str, st[r -- _type] .type) ⊦ r = jvmref
