Hi,

ContentReader cr = fileFolderService.getReader(new NodeRef("noderef"));
InputStream fis = cr.getContentInputStream();
Scanner sc = new Scanner(fis, "UTF-8");
while (sc.hasNextLine()) {
String line = sc.nextLine();
System.out.println(line);
}

With above code 55 MB file reading fine.Without any error.
