The suggestion (feel free to ignore it!) was to take the local variable:

 161         int turns_taken       = 0;

and move it to a field on Context. 

Then in the synchronized block of the main loop sum 'em up. e.g.:

  List<Context> cs = ;
  ...
  int current_total_turns_taken = cs.stream().mapToInt(c -> c.turns_taken).sum();

Obviously that is less efficient but it does separate concerns.
