> While investigating PIG-99, in TestBuiltin.java line 315:
> {code:java}
> for (int i = 0; i < LOOP_COUNT; i++) {
>     for (int j = 0; j < LOOP_COUNT; j++) {
>         sb.append(i + "\t" + i + "\t" + j % 2 + "\n");
>     }
> }
> {code}
> doing "i + "\t" + i + "\t" + j % 2 + "\n"" creates temporary String(s) reducing the advantages of using a StringBuffer.
> Could be replace with:
> {code:java}
> for (int i = 0; i < LOOP_COUNT; i++) {
>     for (int j = 0; j < LOOP_COUNT; j++) {
>         sb.append(i);
>         sb.append("\t");
>         sb.append(i);
>         sb.append("\t");
>         sb.append(j % 2);
>         sb.append("\n");
>     }
> }
> {code}
