    Description

      When I try to update VFS from 2.2 to the newer version. The changes of parseUri breaks the following code:

      @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());
      }
      

      I got an error:

      java.lang.NullPointerException
