Mysterious List behaviour

Question

Hi,
I have a small function, and I don't understand it's behaviour. I hope some can explain me what happens:
public static List findList(JdbcSupport jsi, List list, RMObjectJdbc cls, long Id, String sql, Connection c) throws Exception{
          PreparedStatement ps = jsi.prepareStatement(sql,c);
          ps.setLong(1, Id);
          ResultSet srs = ps.executeQuery();
          int p = 0;  // a query is done and has three results
          for (; srs.next(); ){
               RMObject e = cls.getByIdSimple(srs.getLong(1), c);
               list.add(e); //result is added to list
System.out.println("findList:"+e.getClass().getName()+":"+Id+","+0+","+e.get_id()+","+e.hashCode());
//check properties, "e" really exist
               System.out.println("+"+list.get(p).hashCode());
//also the hashcode of "e" is printed corrctly
               p++;
          for(int i=0;i<list.size();i++){
               System.out.println(i+"-"+list.get(i).hashCode());
// but here, all the elements of the list are replaced by the last, how is that possible?
//that is my question
          srs.close();
          return list;
     }You can see the results of the screen-output
findList:nl.zorggemak.jdbc.orm.openehr.rm.datatypes.basic.DvIdentifierJdbcImpl:1,0,27,766399937

0-766399971
1-766399971
2-766399971
So, why are all three elements of the list replaced by the last added?
It happens outside the loop.
If I don't ant this to happen, what a I do?
Thanks for any help

Thanks for your reply.
It looks like you are right, but as you can see on the output, I think that you are right, stupied, took me all evening to find out, and I did not see it, it is obvious.
Thanks, I will try immediately
