Android metadata exception, e.getMessage () - null

I am currently writing an Android app that uses push notifications. My application successfully registers with Google's servers and receives an identifier, and I have a server-side code that uses this identifier and pushes a notification to the application that is received.

When the click is received, I call the user class, which inside the thread requests the remote server for information that will be processed in the application.

The method is called:

private Thread checkUpdate = new Thread() {
    public void run() {
        try {
            URL updateURL = new URL("http://this.site.com/some/path");
            URLConnection conn = updateURL.openConnection();

            InputStream is = conn.getInputStream();
            BufferedInputStream bis = new BufferedInputStream(is);
            ByteArrayBuffer baf = new ByteArrayBuffer(50);

            int current = 0;
            while ((current = bis.read()) != -1) {
                baf.append((byte) current);
            }

            /* Convert the Bytes read to a String. */
            html = new String(baf.toByteArray());
            mHandler.post(showUpdate);

        } catch (Exception e) {
            // Show message if there was an error with the site.
            Log.e("C2DM", "Exception: " + e.getMessage());

        }

    }
};
