And obtained the following new goals

Proof step 9:
⊦ rk ≠ rk0 → (st[rk0, val][rk]) = st[rk]
Proof step 25:
r -- sk ≠ r1 -- i ', st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r0), is_obj(str, r, st), okarray(r1, byte_type, st), r1 ∈ st, fits(r0, sks0, st), sk ∈ instfields(class), ∀ r, st, r1, i, by, str. fits(r, sks0, st) ∧ okarray(r1, byte_type, st) ∧ r1 ∈ st → (st[r1 -- i ', byteval(by)][r -- sks0]) = st[r -- sks0] ∨ r1 = jvmref ∨ junkref(str, r, st) ⊦ sks0 = [], r1 = jvmref, (st[r1 -- i ', byteval(by)][st[r -- sk] .refval -- sks0]) = st[r -- (sk ' + sks0)], r = jvmref, junkref(str, r, st)
