reg IOException

In my program, I am performing addition of all numbers entered by user at command prompt, I am using Buffered reader to read the input, the program works fine for small data entered but when I past the large amount of data for example around 20 lines each having 4 digits seperated by space I get below exception:

Exception in thread "main" java.io.IOException: Not enough storage is available to process this command
at java.io.FileInputStream.available(Native Method)
at java.io.BufferedInputStream.read(BufferedInputStream.java:321)
at sun.nio.cs.StreamDecoder$CharsetSD.readBytes(StreamDecoder.java:411)

at java.io.BufferedReader.readLine(BufferedReader.java:299)
at java.io.BufferedReader.readLine(BufferedReader.java:362)

Interestingly, if instead of pasting all 20 rows at once if I past 10 rows twice I get output without any exception. Any thoughts whats going on??
                    BufferedReader bufferReader = new BufferedReader(new InputStreamReader(System.in));     
                       int Sum=0;
                                 //number of rows of input
                    int num = Integer.parseInt(bufferReader.readLine());     
                              for(int k=0;k<num;k++){
                                        String[] row = bufferReader.readLine().split(" ");
                                        for(int l=0;l<row.length;l++){
                                             Sum = Sum+Integer.parseInt(row[l]);
                                        }
                                   
                         System.out.println(Sum);
                         Sum=0;
                                             
                    }
