Try with BOMInputStream in apache.commons.io:

public static  T getContent(Class instance, SchemaType schemaType, InputStream stream) throws JAXBException, SAXException, IOException {

    JAXBContext context = JAXBContext.newInstance(instance);
    Unmarshaller unmarshaller = context.createUnmarshaller();
    Reader reader = new InputStreamReader(new BOMInputStream(stream), "UTF-8");

    JAXBElement entry = unmarshaller.unmarshal(new StreamSource(reader), instance);

    return entry.getValue();
}
