I discovered that it is only boundary lines that are affected.

I didn't quite track down the exact cause, but I guess that the
relation members are held in a hash map somewhere and are read out in
an indeterminate order.

Whatever the exact reason, adding a hashCode() method to the Way class
prevents the random ordering, so I shall commit that change.
