             Summary: Changes to parseUri breaks backward compatibility
                 Key: VFS-739
                 URL: https://issues.apache.org/jira/browse/VFS-739
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.4.1, 2.3, 2.4
            Reporter: xia0c


When I try to update VFS from 2.2 to the newer version. The changes of parseUri breaks the following code:
{code:java}
@Test
public void test() throws FileSystemException{
    final String URI = "maprfs:///";
    UrlFileNameParser parser = new UrlFileNameParser();
    FileName name = parser.parseUri(null, null, URI);
    assertEquals(URI, name.getURI());
}
{code}

I got an error:

{code:java}
