Afternote: the new format would have expected comma and blank between 
date and time.

Indeed, that was it.  Setting the property worked as expected, but I 
decided to change creation of DateFormat instances to use exactly the 
format I want.   (There were only a couple of places in my code)

I now use     new SimpleDateFormat("dd.MM.yyyy HH:mm:ss");
The literal String here is really a constant defined in a central place.
That's the spec of the strings I need to parse and it was only "coincidence"
that it even corresponded to German locale before.

Thanks a lot!
