Proof step 11 from proof hasSharing-dups-array (previous step)

st[r -- i '] = st[r -- j '], i < st[r -- _length] .intval, j < st[r -- _length] .intval, is_referencevalue(st[r -- j ']), is_arraytype(st[r -- _type] .type), 0 ≤ i, 0 ≤ j, 0 < st[r -- _length] .intval ⊦ st[r -- j '] .refval = jvmref, i = j, r = jvmref, hasSharing(r, st)

Heuristic elimination applied rule insert elim lemma

And obtained the following new goals

Proof step 10:
st[r -- j '] = refval(r0), st[r -- i '] = st[r -- j '], i < st[r -- _length] .intval, j < st[r -- _length] .intval, is_referencevalue(st[r -- j ']), is_arraytype(st[r -- _type] .type), 0 ≤ i, 0 ≤ j, 0 < st[r -- _length] .intval ⊦ r0 = jvmref, i = j, r = jvmref, hasSharing(r, st)
