A DESCRIPTION OF THE PROBLEM :
unmarshaller.unmarshal(new File("C:\SomeDir#\Foo.xml")) fails with FileNotFoundException even, if the file exists. Seems that javax.xml.bind.helpers.AbstractUnmarshallerImpl.unmarshal( File f ) does not properly url-escape the path, when converting the file object to the url.
There was already an discussion about this issue in 2009, but it seems that no bug was filed.

This bug can be reproduced always.
