James M Snell commented on ABDERA-170:
--------------------------------------

FOMSniffingInputStream and FOMParser are not really meant to be used directly 
like this.  Use this pattern instead:

    //...
    Parser parser = abdera.getParser();
    ParserOptions options = parser.getDefaultParserOptions();
    options.setAutodetectCharset(true);
    
    Document<Element> doc = parser.parse(is, options);
    
    System.out.println(doc.getRoot().toString());    
    System.out.println(doc.getCharset());

FOMParser uses FOMSniffingInputStream internally to do the charset detection.

>             Project: Abdera
>          Issue Type: Bug
>         Environment: linux Ubuntu 7.10, jvm Sun 1.6.0._03, abdera built from 
> trunk source with maven
>            Reporter: Stefano Linguerri
>         Attachments: testentry.xml

>
> This is on Trunk.
> The method FOMParser.parse(InputStream in, String base, ParserOptions 
> options) use FOMSniffingInputStream this class is the problem.
> FOMSniffingInputStream left the mark of inputstrem moved
> So when the input stream is passed to the parser an exception occurs.
> Two stupid test methods for Junit to verify the bug:
> This WORK:
>  @Test
>   public void testXMLFromFileWithoutFOMSniffingInputStream() throws Exception 
> {
>     File file = new File("testentry.xml");
>     Abdera abdera = new Abdera();
>     FileInputStream is = new FileInputStream(file);
>     FOMParser fomParser = new FOMParser(abdera);
>     Document<Element> doc = fomParser.parse(is);
>     doc.getRoot().toString();
>   }
> This THROWS EXECEPTION
>   @Test
>   public void testXMLFromFileWithFOMSniffingInputStream() throws Exception {
>     File file = new File("testentry.xml");
>     Abdera abdera = new Abdera();
>     FileInputStream is = new FileInputStream(file);
>     FOMSniffingInputStream fomSniffingInputStream = new 
> FOMSniffingInputStream(is);
>     fomSniffingInputStream.getEncoding();
>     FOMParser fomParser = new FOMParser(abdera);
>     Document<Element> doc = fomParser.parse(is);
>     doc.getRoot().toString();
>   }
