Exception StackTrace to String

How many times have I forgotten this:

            StringWriter sw = new StringWriter();
            PrintWriter pw = new PrintWriter(sw);
            e.printStackTrace(pw);
            String result = sw.toString();

While we are at it: InputStream to String:

            final StringWriter writer = new StringWriter();
            IOUtils.copy(urlConnection.getInputStream(), writer);
            result = writer.toString();
