And obtained the following new goals

Proof step 12:
⊦ rk ≠ rk0 → (st[rk0, val][rk]) = st[rk]
Proof step 29:
r -- sk ≠ r1 -- fs ', st[r -- sk] = refval(r0), st[r -- _type] .type = mkclasstype(class), sk ∈ instfields(class), is_referencevalue(st[r -- (sk ' + sks0)]), is_bytevalue(st[r1 -- fs ']), fits(r0, sks0, st[r1 -- fs ', byteval(by)]), is_obj(str, r, st), r ≠ r1 ∨ _type ≠ fs ', ∀ r, st, r1, fs, by, str. fits(r, sks0, st[r1 -- fs ', byteval(by)]) ∧ is_bytevalue(st[r1 -- fs ']) ∧ is_referencevalue(st[r -- sks0]) → junkref(str, r, st) ∨ fits(r, sks0, st) ⊦ r = jvmref, junkref(str, r, st), is_referencevalue(st[r -- sk]) ∧ fits(st[r -- sk] .refval, sks0, st)
