Java设置最大堆栈大小 [英] java set max stack size

问题描述

如何设置最大堆栈大小?

How can I set maximum stack size?

我使用jEdit在较大的文件(73 kb)中使用正则表达式进行搜索，但由于StackOverflowException而失败.

I use jEdit to search with regular expression in rather big file (73 kb) and it fails with StackOverflowException.

我尝试设置-Xss40m，但是它似乎是初始堆栈大小，一段时间后它失败，并出现以下异常

I tried to set -Xss40m but it seems to be initial stack size and after some time it fails with following exception

11:45:31 AM [AWT-EventQueue-0] [error] AWT-EventQueue-0: Exception in thread "AWT-EventQueue-0"

如果您能解释为什么抛出OutOfMemory以及如何设置最大堆栈大小，我将不胜感激.

I would appreciate if you explain me why OutOfMemory is thrown and also how to set max stack size.

推荐答案

也许您应该这样设置堆内存大小:

Perhaps you should set the heap memory size as so:

java -Xms 512m -Xmx 1024m
