Java throw e becomes null on Android

I have the following:

     try {
        response.statusCode = urlConnection.getResponseCode();    
     } catch(IOException e) {
        throw e;
     }

I look at the debugger and e = UnknownHostException

After the throw I have:

    try {
        NetworkResponse response = NetworkHelper.getByURL(url);
     } catch(Exception e) {   <------- IT LANDS HERE, BUT e=null
        ExceptionHelper.announce(e);        
        throw e;
    }

So after the throw my catch block gets the exception but it's null. The debugger shows e=null.

I have no idea why this would happen.

I don't even see the point of catching the exception if you just immediately rethrow it. Add a throws IOException to that method and let the other catch handle it.
