Proof step 44 from proof validrefs-not-contains (previous step)

0 < st[r -- _length] .intval, 0 ≤ i, validrefs(str, st[r -- i '] .refval ', st[r -- _type] .type .type, st), is_referencevalue(st[r -- i ']), i < st[r -- _length] .intval, st[r -- _type] .type ≤ ty, is_array(str, r, st) ⊦ r = jvmref, r = st[r -- i '] .refval, st[r -- i '] .refval = jvmref, contains(str, st[r -- _type] .type, st[st[r -- i '] .refval -- _type] .type)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 43:
st[r -- i '] = refval(r0), 0 < st[r -- _length] .intval, 0 ≤ i, validrefs(str, r0 ', st[r -- _type] .type .type, st), is_referencevalue(st[r -- i ']), i < st[r -- _length] .intval, st[r -- _type] .type ≤ ty, is_array(str, r, st) ⊦ r = jvmref, r = r0, r0 = jvmref, contains(str, st[r -- _type] .type, st[r0 -- _type] .type)
