Java 1.6.0.  dom4j SAXReader fails reading file with pathname containing spaces

My program uses dom4j 1.6.1 on Windows (Eclipse)
The following code has always worked up to and including Java 1.5.11

      try {
        SAXReader reader = new SAXReader();
        document = reader.read(filename);      }
      catch (Exception e) {
        e.printStackTrace();
      }

Using Java 1.6.0  the code fails at line
        document = reader.read(filename);      }

It generates a DocumentException (Malformed URL)
The problem lies in the pathname having spaces in the folders (C:/Documents and Settings/blah).
Why should this have changed in Java 6? and is there a solution?
Thanks

the following solution works... but I'd still like to know why the other fails now
      try {
        SAXReader reader = new SAXReader();
        File file = new File(filename);
        document = reader.read(file);      }
      catch (Exception e) {
        e.printStackTrace();
        // do nothing
      }

>>It generates a DocumentException (Malformed URL)

Can you post that exact URL?

Sure CEHJ

It's actually the filepath:

C:\\Documents and Settings\\Owner\\.smartControl\\preferences.xml

Yes, that's not good. Try

document = reader.read(file.toURL());

document = reader.read(file.toURL());      

That would work but so does

document = reader.read(file);
So what's changed in Java 1.6?

I'm not sure the change is in 1.6

Using eclipse with JDK 1.5.11 using the pathName String works fine.
Using eclipse with JDK 1.6.0 it fails - we can switch back and to between
jdk versions to see the problem.
What is worrying is that this has not been reported before.
Jdom seems ok
No big deal though - there are workarounds.

Can you print the output in both cases then (what you did before, but for both)

>> C:\\Documents and Settings\\Owner\\.smartControl\\preferences.xml

Try:

C:/Documents and Settings/Owner/.smartControl/preferences.xml

- should work in both

The problem here is in switching between Java 1.6 and Java 1.5.11
I have tried forward slashes, backward slashes and a mixture of both - makes no difference.
The problem arises when we switch (in Eclipse) to jre 1.6 from jre 1.5.11 - That's it,
nothing else changed. I can toggle between the two platforms as can my colleagues
in another country - same result - Java 1.6 doesn't allow dom4j SAXParser to work with spaces in folder names. I have seen other people complain about this but they received advice like:
"Take out the spaces"  derr!!
or
"Add quotes around the pathname string"  derr!!
Let's now waste anymore time on this because there is a workaround as I posted at the beginning.
Thanks for your efforts

Please report if you find anything else as i'm skeptical about
