OutOfMemoryError while attempting to read 60MB file into HashMap objects

Question

Hi,
I've a 60MB file with about 60000 records that I'm trying to read into a HashMap of <String, String[]>. However, as far as I can see it can only manage reading in 12000 before it falls over with an OutOfMemoryError.
My eclipse.ini contains the following entries:
-Xms40m
-Xmx512m
I've changed Xmx512m to Xmx1024m but this hasn't made a difference.
My program involves reading in the file, sorting it based on 2 attributes of a record and then outputting it in the sorted order.
I've tried a few other methods around just reading in the attributes that I need, doing the sort with those, looking for the rows I need from the input file sequentially and then outputting this in the correct order but this seems to be taking forever, well over 12 hours!
How else can I go about this? Thanks.

Here is the code. Sorry, how do I go about compiling this class as it's looking for the CsvReader jar but can't find. Have tried the -cp option but doesn't seems to work. Thanks.
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.util.HashMap;
import com.csvreader.CsvReader;
public class Reader {
      * @param args
      * @throws IOException
     public static void main(String[] args) throws IOException {
          CsvReader reader = new CsvReader(new FileReader("C:\\temp\\gen_ppl.csv"), '|');
          HashMap<String, String[]> allCorpIDs = new HashMap<String, String[]>();
          while(reader.readRecord())
               allCorpIDs.put(reader.get(0), reader.getValues());
}
