  ****************************************************************
  When the SSL engine is shutting down it tries to retrieve the
  SSL engine but does not check to see if it exists first. This
  leads to the NullPointerException.
  

Problem conclusion

• Added a check to see if SSL engine exists before taking it
  through the shutdown process.
