Querying columns return strange characters

[Ivan Chang]

I modified some test cases in the Cassandra distribution.  Specifically in
the unit test package I modified ServerTest.java, basically just tried to
insert some columns and retrieve them.  Here's part of the code:

        RowMutation rm = new RowMutation("Table1", "partner0");
        ColumnFamily cf = new ColumnFamily("Standard1", "Standard");
        long now = Calendar.getInstance().getTimeInMillis();
        System.out.println(now);
        cf.addColumn("firstname", "John".getBytes(), now);
        cf.addColumn("lastname", "Doe".getBytes(), now);
        rm.add(cf);
        try {
            rm.apply();
        } catch (Exception e) {
        }

        Table table = Table.open("Table1");

        try {
            Row result = table.getRow("partner0", "Standard1");
            *System.out.println(result.toString());*
            ColumnFamily cres = result.getColumnFamily("Standard1");
            Map cols = cres.getColumns();
            *System.out.println(cols.size());*
            Set c = cols.keySet();
            Iterator it = c.iterator();
*            while (it.hasNext()) {
                String cn = (String) it.next();
                System.out.println(cn);
                //Byt/eArrayOutputStream baos = new ByteArrayOutputStream();
                /DataOutputStream dos = new DataOutputStream(baos);
                //cres.getColumnSerializer().serialize(cres.getColumn(cn),
dos);
                //dos.flush();
                //System.out.println(dos.size());
                //System.out.println(dos.toString());
                System.out.println(cres.getColumn(cn).value().toString());
            }*

//System.out.println(cres.getColumn("firstname").value().toString());
        } catch (Exception e) {
            System.out.println(e.getMessage());
        }

In summary, it's a very simple code that inserts a row (key "partner0") with
two columns: firstname (value "John"), lastname (value "Doe") to the
Standard1 column family.  When I execute the test, I got the following
output:

   [testng] 1245082940509
   [testng] Row(partner0 [ColumnFamily(Standard1
[firstname:false:4...@1245082940509, lastname:false:3...@1245082940509]))]
   [testng] 2
   [testng] lastname
   [testng] [...@dcb03b
   [testng] firstname
   [testng] [...@b60b93

Everything looks fine, the columns were inserted.  However, the retrieved
values were [...@dcb03b for lastname and [...@b60b93 for firstname, instead of
what's inserted by the code ("Doe", "John").

Anyone could give a clue as to why this happened?

Thanks!
