Proof step 34 from proof validrefs-not-in (conclusion)

⊦ r ∈ refs ∧ r ≠ jvmref ∧ ¬ (is_valid_ref(r, st) ∧ type∃(str, st[r -- _type] .type)) → ¬ validrefs(str, refs, ty, st)

Heuristic simplifier applied rule simplifier

And obtained the following new goals

Proof step 33:
r ∈ refs, validrefs(str, refs, ty, st) ⊦ r = jvmref, is_valid_ref(r, st) ∧ type∃(str, st[r -- _type] .type)
