Java的双重自由或腐败

Question

也许是愚蠢的问题，但是运行* .jar包时出现随机跟踪错误。有时programm可以完美运行，有时会中断将其放到控制台中：

Answer 1

我知道这是一个旧线程，但以防万一有人在同一错误中失败。

这是您正在使用的本机库的多线程问题。

长话短说，java将本机库加载到内存中，然后由多个线程同时访问它，然后弹出此错误。

此问题的快速解决方法是将生成此错误的方法标记为synchronized。

@kit注释后更新。

在多线程环境中无法运行此类本机库。

您的选择是：

• 修改本机库以使其具有线程安全性（如果您可以访问其代码）。
• 将其包装为应用程序并作为单独的进程运行多个副本（因为每个进程一次加载本机库）
• 将其包装为服务并运行多个副本，并使用套接字或适当的更高级别的RPC机制与其进行通信。
