JNI错误记录--JNI程序调用本地库时JVM崩溃

什么是JNI内存泄露，基本的避免方法 ：

http://www.ibm.com/developerworks/cn/java/j-lo-jnileak/

最近的课题中需要用到Spark，同组同学负责的算法用c++写的，数据库读取及调用算法用的是java，因此在整合的时候用到了jni。

因为任务需要并行，因此想到了用多线程实现。

程序在单机单线程的情况下运行没问题，当开两个线程的时候就出现了如下错误：

问题分析：

查阅网上资料，可能原因是内存泄露。

原因是调用c++库的内容有错误。

逐步定位，经检查，发现是代码中初始化数据的时候出现了问题

 

在这个过程中学习了JNI,JVM结构以及内存管理
