问题描述
也许是愚蠢的问题，但是运行* .jar包时出现随机错误.有时programm可以完美运行，有时会中断将其放到控制台中:
maybe stupid question but i'm getting randomly following error when running my *.jar package. Sometimes programm runs flawlessly and sometimes interrupts putting this out in console:
*** Error in 'java': double free or corruption (out): 0x00007f665c04a830 ***

我正在使用64位Ubuntu 13.10，并运行:
I'm using Ubuntu 13.10 64-bit, running:
java version "1.7.0_51"
OpenJDK Runtime Environment (IcedTea 2.4.4) (7u51-2.4.4-0ubuntu0.13.04.2)
OpenJDK 64-Bit Server VM (build 24.45-b08, mixed mode)
感谢您的帮助:)
推荐答案
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.
I know that this is an old thread but just in case someone fails in the same error.
这是您正在使用的本机库的多线程问题.
This is a multi-threading issue with a native library you are using.
长话短说，java将本机库加载到内存中，然后由多个线程同时对其进行访问，然后弹出此错误.
To cut the long story short, the java loads the native library into memory then it is accessed by multiple threads at the same time, then this error pops up.
此问题的快速解决方法是将生成此错误的方法标记为 synchronized .
A quick workaround for this issue is to mark the method that generating this error as synchronized.
不可能在多线程环境中运行此类本机库.
It is not possible to run such native library in multi-threading environment.
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Sockets或适当的更高级别的RPC机制与其进行对话.
