I get the cited warning message in a project I'm working on.

URLReader's signature is  public static String readURL(URL url)

And indeed the method that calls it is not static.

But I don't really understand why it would generate a warning or how one
could solve it.

The readURL method only uses local variables (and the parameter) so it
doesn't need to not be static (if I understand when static gets used).

Full method is below.

Thanks

 public static String readURL(URL url){
  StringBuffer sb = new StringBuffer();
  String s = "";
  InputStream is = null;
  BufferedInputStream bis = null;
  InputStreamReader isr = null;
  BufferedReader br = null;
  try{
   is = url.openStream();
   bis = new BufferedInputStream(is);
   isr = new InputStreamReader(bis);
   br = new BufferedReader(isr);
   do {
    s = br.readLine();
    if (s != null){
     sb.append(s);
    }
   } while (s != null);
  }catch (IOException e){
   System.err.println("Error in URLReader while reading: " +
e.getMessage());
  }finally{
   try{
    br.close();
    isr.close();
    bis.close();
    is.close();
   }catch (Exception e){
    System.err.println ("Error in URLReader when closing up: " +
e.getMessage());
   }
   is = null;
   bis = null;
   isr = null;
   br = null;
   s = null;
  }
  return sb.toString();
 }
