Proof step 31:
st[r -- _type] .type = mkclasstype(class), (st[r1 -- fs ', byteval(by)][r -- sk]) = refval(r0), is_obj(str, r, st), fits(r0, sks0, st[r1 -- fs ', byteval(by)]), is_bytevalue(st[r1 -- fs ']), is_referencevalue(st[r -- (sk ' + sks0)]), is_classtype(st[r -- _type] .type), sk ∈ instfields(class), ∀ 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 ≠ r1 ∨ _type ≠ fs ' ⊦ r = jvmref, junkref(str, r, st), is_referencevalue(st[r -- sk]) ∧ fits(st[r -- sk] .refval, sks0, st)
