提高Android的MaxJavaStackTraceDepth

Question

我遇到了一个很难调试的StackOverFlowError，由于堆栈跟踪的深度有限，我无法找到问题的根源。

是否有可能像-XX:MaxJavaStackTraceDepth=1000000一样增加安卓系统的-XX:MaxJavaStackTraceDepth=1000000？

我不确定这是否有趣，但下面是当前的堆栈跟踪：

由于日志记录系统的限制，而不是堆栈深度的限制，输出被切断了。最简单的方法是减少设备上的堆栈深度，使其更快地失败，堆栈跟踪符合4K日志消息。

如果自己创建线程，则可以在线程构造函数中配置堆栈大小。看起来这可能是由线程池创建的，因此您需要提供一个使用ThreadFactory的适当构造函数。

有一次，我为android.util.Log编写了一个修补程序，它检测到了这种情况，并去掉了跟踪的中间部分，留下了开始和结束，但我从未使它做好生产准备。
