And obtained the following new goals

Proof step 40:
dups(refs1) ∨ r ∈ refs1, validrefs(str, r ' + refs1, st[r -- _type] .type, st), is_array(str, r, st) ⊦ r = jvmref, ¬ r ∈ refs1 ∧ ¬ dups(refs1), (dups(refs1) ∨ r ∈ refs1) ∧ validrefs(str, r ' + refs1, mkclasstype(`java.lang.Object' .class), st)

Rule argument
