  From this root cause of the problem is EOFException thrown at
  org.bson.io.Bits.readFully(Bits.java:75)
  
  This EOFException is caused by socket closed by jsonListener.
  It is that the listener.idle.timeout does not work on 5.0.8.4.
  The listener.idle.timeout starts to work on 5.0.8.5 and causes
  connection close.
