And obtained the following new goals

Proof step 29:
st[r -- _type] .type = mkarraytype(ty), st[r -- i '] = refval(r0), is_array(str, r, st), fits(r0, sks0, st), is_shortvalue(st[r1 -- fs ']), junkref(str, r0, st), is_arraytype(st[r -- _type] .type), i < st[r -- _length] .intval, 0 < st[r -- _length] .intval, 0 ≤ i ⊦ r = jvmref, sks0 = [], (st[r1 -- fs ', val][r0 -- sks0]) = st[r0 -- sks0], ∃ i0. ¬ i0 < 0 ∧ ¬ st[r -- _length] .intval ≤ i0 ∧ is_referencevalue(st[r -- i0 ']) ∧ st[r -- i0 '] .refval ≠ jvmref ∧ (¬ st[st[r -- i0 '] .refval -- _type] .type ≤ ty ∨ junkref(str, st[r -- i0 '] .refval, st))
