RuntimeError: release unlocked lock during running Dab Compliance suite when client lost network and reconnects

[panpakr]

Hi ,

I have experienced one issue in running dab compliance on the client device which connects after wifi failure .
I have added few log in dab_client.py to check

Testing on message Lock : <unlocked _thread.lock object at 0x7f17fd8172a0> Self : <dab_client.DabClient object at 0x7f17fd817310> Client: <paho.mqtt.client.Client object at 0x7f17fd8170a0>
Lock is False
Reponse {'status': 200}
Exception in thread Thread-1:

self.__lock.release()
RuntimeError: release unlocked lock
App started?(Y/N)

As for log traces I found self.__lock.release() is called mulitple times

def __on_message(self, client, userdata, message):   
    self.__response_dic = json.loads(message.payload)
    self.__lock.release()
    try:
        self.__code = self.__response_dic['status']
    except:
        self.__code = -1

Is this a known issue from DAB suite or Paho Mqtt client library ?

I have tried like this ,but it spawn another issue in Dab Compliance
if(self.__lock.locked()):
self.__lock.release()
