您的应用程序是否会生成任何子线程？如果有，你确保你终止它们（假设它们不是守护程序线程）？

Does your application spawn any child threads? If so have you ensured that you terminate them (assuming that they're not daemon threads)?

如果你的应用程序产生非守护程序线程那么它们（以及你的应用程序） ）将继续活着，直到你杀死这个过程为止

If your application spawns non-daemon threads then they (and therefore your app) will continue to live on until such time you kill the process
