Exception during processing XSLT transformation!

Question

I'm using this code to generate contents file.

try {
        StreamResult result = new StreamResult();
        TransformerFactory tf = TransformerFactory.newInstance();
        Templates templ =  tf.newTemplates(xsltSource);
        Transformer transf = templ.newTransformer();
        for (String item: groups){
            item = item.replaceAll(" ", "-").toLowerCase();
            result.setOutputStream(new FileOutputStream(path+item+".html"));
            transf.clearParameters();
            transf.setParameter("group", item);
            transf.transform(xmlSource, result);
        }
    } catch (TransformerConfigurationException e) {
    throw new SinkException(e.getMessage());
    } catch (TransformerException e) {
    throw new SinkException(e.getMessage());
    }

But on second iteration I have an exception

ERROR: javax.xml.transform.TransformerException: com.sun.org.apache.xml.internal.utils.WrappedRuntimeException: Read error

Cann't understand what is the reason?

Thank a lot for assistance. Th error was in not properly closed Source resource. Was:

Source xmlSource = new StreamSource(new FileInputStream(path+Constants.MANIFEST_FILE_NAME));

Fixed:

Source xmlSource = new StreamSource(path+Constants.MANIFEST_FILE_NAME);
