Issue2864

I seem to have a very odd issue. If I use two PythonInterpreters to make two calls into httplib, the second invocation causes an error:

The Java usage of PythonInterpreter is:

    public static void main(String[] args) {
        try {
            PythonInterpreter pythonInterpreter = new PythonInterpreter();
            pythonInterpreter.exec("import httplib");
            pythonInterpreter.exec("print 'first invocation'");
            pythonInterpreter.exec("con = httplib.HTTPSConnection('slack.com')");
            pythonInterpreter.exec("con.request('GET', '/intl/en-gb/?eu_nc=1')");
            pythonInterpreter.close();

            pythonInterpreter = new PythonInterpreter();
            pythonInterpreter.exec("import httplib");
            pythonInterpreter.exec("print 'second invocation'");
            pythonInterpreter.exec("con = httplib.HTTPSConnection('slack.com')");
            pythonInterpreter.exec("con.request('GET', '/intl/en-gb/?eu_nc=1')");
            pythonInterpreter.close();
        } catch (Exception e) {
            System.out.println("Failed:");
            e.printStackTrace();
        }
    }


Results in:

first invocation
second invocation

java.util.concurrent.RejectedExecutionException: java.util.concurrent.RejectedExecutionException: event executor terminated
Failed:

Essentially, the second call to 'con.request()' results in the exception: java.util.concurrent.RejectedExecutionException: java.util.concurrent.RejectedExecutionException: event executor terminated


Can someone help me please?
