Proof step 19:
st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r0), is_obj(str, r, st), is_referencevalue(st[r -- (sk ' + sks0)]), is_bytevalue(st[r1 -- fs ']), fits(r0, sks0, st), sk ∈ instfields(class), r ≠ r1 ∨ sk ≠ fs ', r ≠ r1 ∨ _type ≠ fs ', is_referencevalue(st[r0 -- sks0]) → junkref(str, r0, st) ⊦ r = jvmref, fits(r0, sks0, st[r1 -- fs ', byteval(by)]), sk .fs ' ∈ instfields(class) ∧ is_referencevalue(st[r -- sk .fs ']) ∧ st[r -- sk .fs '] .refval ≠ jvmref ∧ (¬ st[st[r -- sk .fs '] .refval -- _type] .type ≤ sk .fs .type ∨ junkref(str, st[r -- sk .fs '] .refval, st))
