[android-developers] UnknownHostException is not logged

I was racking my brain, trying to figure out why one of my users was having trouble connecting and nothing was in the logs.  Finally I looked at the Android source and realized that the logging code explicitly ignores UnknownHostException.  Even worse, the Javadoc doesn't specify this behavior.

Does this sound like a bug to anyone, as opposed to a feature?  In my case, the user enters the hostname, so it's possible to get this exception while the user has a network connection.

    /**
     * Handy function to get a loggable stack trace from a Throwable
     * @param tr An exception to log
     */
    public static String getStackTraceString(Throwable tr) {
        if (tr == null) {
            return "";
        }

        // This is to reduce the amount of log spew that apps do in the non-error
        // condition of the network being unavailable.
        Throwable t = tr;
        while (t != null) {
            if (t instanceof UnknownHostException) {
                return "";
            }
            t = t.getCause();
        }

        StringWriter sw = new StringWriter();
        PrintWriter pw = new PrintWriter(sw);
        tr.printStackTrace(pw);
        return sw.toString();
    }
