Proof step 7 from proof junkref-addarray-04 (previous step)

is_reftype(ty), type∃(str, ty), newref(r, st), validreflist(str, vals, ty, st), junkref(str, r, addarray(r, ty, vals, st)) ⊦ r = jvmref, ty .jtelemtype = abstract_type, ty .jtelemtype = void_type, is_array(str, r, addarray(r, ty, vals, st))

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 2:
⊦ ty .jtelemtype ≠ void_type ∧ ty .jtelemtype ≠ abstract_type ∧ type∃(str, ty) ∧ (∀ val. val ∈ vals → okval(val, ty)) ∧ r ≠ jvmref → is_array(str, r, addarray(r, ty, vals, st))
Proof step 6:
¬ (ty .jtelemtype ≠ void_type ∧ ty .jtelemtype ≠ abstract_type ∧ type∃(str, ty) ∧ (∀ val. val ∈ vals → okval(val, ty)) ∧ r ≠ jvmref), is_reftype(ty), type∃(str, ty), newref(r, st), validreflist(str, vals, ty, st), junkref(str, r, addarray(r, ty, vals, st)) ⊦ r = jvmref, ty .jtelemtype = abstract_type, ty .jtelemtype = void_type, is_array(str, r, addarray(r, ty, vals, st))
