Oh, may I ask another question then? Do any threads allowed to move when a losing/winning message appear? I thought they are allowed to move so it caused the (1) problem. But if not allowed, then I understand why it is the race problem. |

You can disallow them to move when a message pops up. |

Judging from other discussions, it is also possible that you return null instead of an empty array when all player die (i.e., game ends and no winners). |

Did it return to main after all players lost? I think I return empty array but it seems like i am only in main menu after all players lose. |

Ok, i found that there was a logic error in my code |

That is the race you need to deal with when doing multithreading programing. The consistent behavior should be that there is only one winning message.
If two winning messages pop up, the
serializabilityproperty is violated, i.e., if we only use one thread to deal with all players, there is never the case that two winning messages are shown.It should go back to main menu. It should be a bug. But, this is not part of the grading scheme of PA3. So whether or not returning to main menu will not affect the hidden tests.
