Can anyone explain why this is printed to console on startup ?

orderByFragment(order-by)

sortSpecification({sort specification})

sortKeySpecification(sort key)

sortKey($PlaceHolder$.stageinprogram)

< sortKey(null)

< sortKeySpecification(null)

< sortSpecification(null)

< orderByFragment(null)
