Getting error 400 while hitting twitter API since 16 Nov 2012


Hi all, I am developing an Twitter Application using REST API. since 16 Nov 2012 Evening i am constantly getting error 400 for every HTTP request.
But this is not reproduced when i used Twitter4J.

I am using signpost-core- for signing the request. here snippet of code in Java :

OAuthConsumer consumer = new DefaultOAuthConsumer(“consumer_key”,“Consumer_secret”);
consumer.setMessageSigner(new HmacSha1MessageSigner());
consumer.setTokenWithSecret(“Access_token”, “secret”);
URL url = new URL(“”);
HttpURLConnection request = (HttpURLConnection) url.openConnection();
System.out.println("Response: " + request.getResponseCode() + " "+ request.getResponseMessage());
