Proof step 26:
st[r -- _type] .type = mkclasstype(class), st[r -- sk] = refval(r0), is_obj(str, r, st), r1 ∈ st, is_referencevalue(st[r -- (sk ' + sks0)]), okarray(r1, byte_type, st), fits(r0, sks0, st[r1 -- i ', byteval(by)]), is_classtype(st[r -- _type] .type), sk ∈ instfields(class), ∀ st, r, r1, i, by, str. is_referencevalue(st[r -- sks0]) ∧ okarray(r1, byte_type, st) ∧ fits(r, sks0, st[r1 -- i ', byteval(by)]) ∧ r1 ∈ st → r1 = jvmref ∨ fits(r, sks0, st) ∨ junkref(str, r, st) ⊦ r1 = jvmref, r = jvmref, r = r1, junkref(str, r, st), fits(r0, sks0, st)
