java double free or corruption

Question

这可能是个愚蠢的问题，但我在运行 *.jar 包时随机出现以下错误。有时程序运行完美，有时会中断，将其输出到控制台:

我正在使用 Ubuntu 13.10 64 位，正在运行:

java version "1.7.0_51"

感谢您的帮助:)

Answer 1

我知道这是一个旧线程，但以防有人因同样的错误而失败。

This is a multi-threading issue with a native library you are using.

长话短说，java将本地库加载到内存中，然后被多个线程同时访问，然后弹出这个错误。

此问题的快速解决方法是将生成此错误的方法标记为同步。

@kit评论后更新。

无法在多线程环境中运行此类 native 库。

您的选择是:

• 修改 native 库以使其成为线程安全的(如果您有权访问其代码)。
• 将其包装为一个应用程序并将多个副本作为单独的进程运行(因为每个进程加载一次 native 库)
• 将其包装为一项服务并运行多个副本，使用套接字或适当的更高级别的 RPC 机制与其通信。
