Error stream is not accessible in Android

[datalogics-alexk]

In Android, certain HTTP request errors cause an IOException to be thrown in the Response constructor that is called by Request.send(). This prevents the caller from getting access to Response#getStream(), which makes it difficult to handle specific errors.

Android documentation for HTTPUrlConnection, states that if HttpUrlConnection#getInputStream() throws an IOException, then HttpUrlConnection#getErrorStream() may be called in order to read the error response from the server.
