Comment (by iwakeh):

 It is not necessary to use the "new" Main class.

 I reproduced the problem using the old version on master.
 Just run the background app starting from scratch.
 And at some point there seems to be a data situation that
 the initial wait() in hasNext() is called, but no notifyAll() or notify()
 can occur later.
