Proof step 48 from proof junkref-addarray-01 (previous step)

vals[i→n(i)] = refval(r0), i < n→i(# vals), class∃(str, class), newref(r, st), is_array(str, r, addarray(r, mkclasstype(class), vals, st)), 0 ≤ i, junkrefs(str, r0 ' + refs, mkclasstype(class), addarray(r, mkclasstype(class), vals, st)), st[r0 -- _type] .type ≤ mkclasstype(class) ⊦ r = jvmref, vals = [], r0 = jvmref, junkref(str, r0, st)

User applied rule insert rewrite lemma

And obtained the following new goals

Proof step 41:
⊦ junkref(str, r, st) ↔ (∃ refs. refs ≠ [] ∧ refs .first = r ∧ junkrefs(str, refs, st[r -- _type] .type, st))
Proof step 47:
vals[i→n(i)] = refval(r0), i < n→i(# vals), class∃(str, class), newref(r, st), is_array(str, r, addarray(r, mkclasstype(class), vals, st)), 0 ≤ i, junkrefs(str, r0 ' + refs, mkclasstype(class), addarray(r, mkclasstype(class), vals, st)), st[r0 -- _type] .type ≤ mkclasstype(class) ⊦ r = jvmref, vals = [], r0 = jvmref, ∃ refs. refs ≠ [] ∧ refs .first = r0 ∧ junkrefs(str, refs, st[r0 -- _type] .type, st)

Rule argument
