Type of Change

Fixture to handle PubNub Client Destroy Gracefully in case JobQueue is already closed(non-breaking changes which adds functionality)

Description

Problem

• I was implementing the reinitialize pubnub client mechanism in my application, So before reinitializing it, I was calling the inbuilt Destroy() func for cleaning all open requests, removing listeners, etc. It was throwing panic with the error mentioned below

• Code In which it was panicking
  p.client.Destroy()
  lib code snapshot
  
  panic Error
  

Solution

• Added the condition to check if it is already closed or not before closing it

Tested

• Tested locally
  I was able to destroy the client connection gracefully and reinitialize the client connection in case of any pubnub system status events
