Proof step 46:
st[r -- sk] = refval(r0), is_shortvalue(st[r1 -- fs ']), fits(r0, sks0, st), is_referencevalue(st[r -- sk]), r ≠ r1 ∨ sk ≠ fs ', ∀ st, r1, fs, r, val, str. is_shortvalue(st[r1 -- fs ']) ∧ fits(r, sks0, st) → (st[r1 -- fs ', val][r -- sks0]) = st[r -- sks0] ∨ junkref(str, r, st), is_arraytype(st[r -- _type] .type) → is_indexkey(sk) ∧ 0 ≤ sk .index ∧ sk .index < st[r -- _length] .intval, is_classtype(st[r -- _type] .type) → sk ∈ instfields(st[r -- _type] .type .class) ⊦ r = jvmref, (st[r1 -- fs ', val][(st[r1 -- fs ', val][r -- sk]) .refval -- sks0]) = st[r -- (sk ' + sks0)], sks0 = [], junkref(str, r, st)
