title: file returning null on reading
body: <p>I have the following code: </p>
  
  <pre><code>FileReader fileReader = new FileReader(textfilename);
  BufferedReader bufferedReader = new BufferedReader(fileReader);
  System.out.println(bufferedReader.readLine());
  </code></pre>
  
  <p>To read the text file, I pass the path of the text file through the textfilename variable. 
  I have tried with 10 different files and only the file with a particular name returns null on reading the first line. Others can be easily read. </p>
  
  <p>I cannot change the name of the file though. </p>
  
  <p>What could be the error? </p>
  
  <p>Thanks in advance. </p>
