I am getting the following error message when trying to utilise an osm pbf from the Geofabrik (latest Europe file):

```
org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 1; Content is not allowed in prolog.

```

The information on it seem to be more Java related than OSM, but I might be mistaken and it has something to do with white spaces in the osm file.

Can somebody help here?
