Cannot access to root cause of Py4JNetworkError Exception.

[MahsaSeifikar]

It seems there is a bug in send_command function in 'java_gateway.py'. When an exception is raised the current version of code doesn't reveal the cause of exception

 except Py4JNetworkError as pne:
 if connection:
                reset = False
                if isinstance(pne.cause, socket.timeout):
                    reset = True
                connection.close(reset)
            if self._should_retry(retry, connection, pne):
                logging.info("Exception while sending command.", exc_info=True)
                response = self.send_command(command, binary=binary)
            else:
                logging.exception(
                    "Exception while sending command.")
                response = proto.ERROR

In my use case, I need to access to reason of exception in the answer in __call__ function in java_gateway.py.
