Issue2722

This is my code:

import java.util.Properties;
import org.python.util.PythonInterpreter;

public class GenerateWeather {

	@SuppressWarnings("resource")
	public static void main(final String[] args) throws ScriptException {
		System.setProperty("python.cachedir.skip", "true");
		Properties p = new Properties();
		p.setProperty("python.path",
				"/Users/<user>/.m2/repository/org/python/jython-standalone/2.7.1/jython-standalone-2.7.1.jar");
		p.setProperty("python.home",
				"/Users/<user>/.m2/repository/org/python/jython-standalone/2.7.1/jython-standalone-2.7.1.jar");
		p.setProperty("python.prefix",
				"/Users/<user>/.m2/repository/org/python/jython-standalone/2.7.1/jython-standalone-2.7.1.jar");
		PythonInterpreter.initialize(System.getProperties(), p, new String[] {});

		PythonInterpreter interpreter = new PythonInterpreter();

		interpreter.exec("import sys");
		interpreter.exec("sys.path.append(\"/usr/local/lib/python2.7/site-packages\")");
		interpreter.execfile("/Users/<user>/GenerateWeatherReport/python/current_and_forecast.py");
	}
}

*******
current_and_forecast.py works great when invoked in stand-alone mode "python current_and_forecast.py" however fails with Jython with the following stack-trace:

AttributeError: 'org.python.netty.channel.socket.nio.NioSocketChann' object has no attribute 'bytesBeforeUnwritable'

*********
when checked with Weather API or urllib3, the suggestions were to reach out to Jython because of some native issue with sockets.

Pls can you help me out here. Thanks.
