>             Project: Axis 2.0 (Axis2)
>          Issue Type: Improvement
>          Components: modules
>    Affects Versions: 1.6, 1.5

> The method getJSONString() in AbstractJSONDataSource makes
> use of string concatenation instead of using a buffer (e.g. StringBuilder).
>                 char temp = (char)jsonReader.read();
>                 jsonString = "";
>                 while ((int)temp != 65535) {
>                     jsonString += temp;
>                     temp = (char)jsonReader.read();
>                 }
> A buffer would be nice for printing large JSON-strings (e.g. with 40000 characters)
> or a printing a lot of middle-sized JSON-strings.
>                 char temp = (char)jsonReader.read();                
>                 StringBuilder sb = new StringBuilder(100); // TODO which initial capacity?
>                 while ((int)temp != 65535) {
>                     sb.append(temp);
>                     temp = (char)jsonReader.read();
>                 }
>                 jsonString = sb.toString();
