BufferedReader not closed warning not disappearing

Question

I am using a BufferedReader, and though I call the close() method, eclipse still gives me a warning. Eclipse does not give me a warning if I place the close() call before the while, but in then the code does not work. Is there either an error in my code, or what else is the problem? Code:

    Hashtable<String, Hashtable<String, Integer>> buildingStats = new Hashtable<String, Hashtable<String, Integer>>();
    try 
    {
        BufferedReader br = new BufferedReader(new FileReader(new File("Assets/Setup/Buildings.txt"))); // Sets the buildings values to the values in Buildings.tx
        String line;
        int lineNum = 0;
        while((line = br.readLine()) != null)
        {
            ++lineNum;
            String[] values = line.split(",");
            if (values.length != 3)
                throw new Exception("Invalid data in Assets/Setup/Buildings.txt at line " + lineNum);
            if (buildingStats.containsKey(values[0]))
            {
                buildingStats.get(values[0]).put(values[1], Integer.parseInt(values[2]));
            }
            else 
            {
                buildingStats.put(values[0], new Hashtable<String, Integer>());
                buildingStats.get(values[0]).put(values[1], Integer.parseInt(values[2]));

            }

        }
        br.close();
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }
    return buildingStats;

You should put it in a finally method like so:

BufferedReader br = null;
try {
    br = new BufferedReader(new FileReader(new File("Assets/Setup/Buildings.txt")));
    // do things
} catch (Exception e){
   //Handle exception
} finally {
    try {
        br.close();
    } catch (Exception e){}
}

If you still get the warning try cleaning and rebuilding your eclipse project.
