大家能不能帮忙看一下这份java的错误日志，是关于jni的，跪求帮忙
这里贴不了全部的内容，如果想看全部内容的话可以发给你，大家帮帮忙，具体情况是开一条线程调用时是正常，但是线程越多就越容易出错。

[解决办法]
开了多少线程，貌似线程的栈空间不够
设下 stack大小
-----------------来源于网络----------------------
Stack的设定
每个线程都有他自己的Stack。
-Xss
每个线程的Stack大小
Stack的大小限制着线程的数量。如果Stack过大就好导致内存溢漏。-Xss参数决定Stack大小，例如-Xss1024K。如果Stack太小，也会导致Stack溢漏。
