> In-memory evaluation of expression fails with UnsupportedOpeartionException depending on order of corresponding null comparison and value comparison nodes. E.g.
> Artist.BIRTH_DATE.gt(date).orExp(Artist.BIRTH_DATE.eq(null)))
> will fail if it will encounter null among Session.startDate values, but 
> Artist.BIRTH_DATE.eq(null).orExp(Artist.BIRTH_DATE.gt(date)) 
> will be evaluated successfully.
