解决maven的一个StackOverflowError

今天在用 “debug” 模式运行 maven 的 jetty:run 时,出现了 java.lang.StackOverflowError ,具体的栈信息如下:

1

8
9
10
11

The system is out of resources.
Consult the following stack trace for details.

Google 了一下,了解到解决 java.lang.StackOverflowError 的一种办法是增大栈的大小:

1
-Xss你想增加到的大小

由于我是用 idea 启动的 debug,所以要在 idea 中设置,设置选项的位置如下:

调成了栈大小后,重新 debug 发现不再 StackOverflowError 了。
