And obtained the following new goals

Proof step 31:
st[r0 -- i '] = refval(r2), st[r0 -- _type] .type ≤ ty, 0 ≤ i, 0 < st[r0 -- _length] .intval, is_array(str, r0, st), i < st[r0 -- _length] .intval, is_referencevalue(st[r0 -- i ']), junkrefs(str, r2 ' + refs, st[r0 -- _type] .type .type, st), ∀ str0, ty0, st0, r1. junkrefs(str0, r2 ' + refs, ty0, st0) → junkrefs(str0, r2 ' + refs, ty0, st0 -- r1) ⊦ r = r0, r0 = jvmref, junkrefs(str, r0 ' + r2 ' + refs, ty, st -- r)
