DataUtilities.urlToFile doesn't handle network paths correctly
--------------------------------------------------------------
Key: GEOT-3300
URL: http://jira.codehaus.org/browse/GEOT-3300
Project: GeoTools
Issue Type: Bug
Components: data
Affects Versions: 2.6.5
Reporter: Patrick Nagelschmidt
Priority: Minor
Currently in uDig you can open a map from a windows network share (samba)
without problems, but if you save and re-open the project again the path is
treated as local and the file not found. The culprit seems to be
{{org.geotools.data.DataUtilities.urlToFile}}.
If you create an URL object containing a windows network share like this
{noformat}
new URL("file", "////oehhwsfs09", "/some/path/on/the/server/filename.nds");
{noformat}
and pass it to {{org.geotools.data.DataUtilities.urlToFile(URL)}}, as it's done
automatically if e.g. uDig saves a project, the {{URL}} object will be
transformed into a plain string and that will be passed to the {{File}}
constructor. This works, i.e. the file can be opened, but from that point on
the file's network nature is lost, which means the filesystem normalizer of
{{Java.io.File}} will remove the leading double slashes and threat the file as
local. Imo you should call {{Java.io.File(URI)}} instead of
{{Java.io.File(String)}} at the end of {{urlToFile}} to make sure a set
authority field in the {{URL}} is preserved.
