无法追踪堆栈溢出错误的来源

我有一个作为服务运行的 Java 应用程序。运行几天后，我收到堆栈溢出错误。问题是我的源代码中产生错误的堆栈帧不在 printStackTrace 函数报告的错误中。我不知道如何找到问题所在。

这是 printStackTrace 的结果：

java.lang.StackOverflowError
    at java.util.LinkedList.listIterator(LinkedList.java:684)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
        ... (this is repeated hundreds of times)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)

原文

I have a Java application that is working as a service. After several days running I get a stack overflow error. The problem is that the stack frame in my source where the error is being originated is not in the error reported by printStackTrace function. I have no idea about how to find where the problem is.

This is the result of printStackTrace:

java.lang.StackOverflowError
    at java.util.LinkedList.listIterator(LinkedList.java:684)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
        ... (this is repeated hundreds of times)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)
    at java.util.SubList.listIterator(AbstractList.java:699)
    at java.util.SubList$1.<init>(AbstractList.java:700)

您的问题可以重现如下：

List<String> l = ...;

for (int i = 0; i < 2800; i++) {
    l = l.subList(...);
}
l.listIterator(...);

因此，请注意 subList() 的所有调用，并确保它们不会形成如上所述的长子列表链。

这样的链是一个递归结构（每个子列表都保留对其父列表的引用），在很长的链上调用listIterator()会导致非常深的递归，从而导致堆栈溢出。

Your problem can be reproduced as follows:

List<String> l = ...;

for (int i = 0; i < 2800; i++) {
    l = l.subList(...);
}
l.listIterator(...);

So, pay attention on all invocations of subList() and make sure they don't form a long chain of sublists as above.

Such a chain is a recursive structure (each sublist keeps a reference to its parent list), and calling listIterator() on a very long chain causes a very deep recursion which causes stack overflow.
