log4j堆栈溢出

Question

这是stackoverflow站点上的一个真正的stackoverflow异常！我只是想知道以前是否有人见过它-以及他们用什么来解决它。

java.lang.StackOverflowError

Answer 1

此处缺少log4j配置文件和代码。

但最初的猜测是

1)在代码中的某处使用LoggingOutputStream，替换System.err如下所示：

System.setErr(new PrintStream(new LoggingOutputStream(Category.getRoot(), Priority.WARN), true));

2) log4j配置不正确，尝试将内部错误打印到LogLog中的System.err。

这会创建循环日志记录调用，从而导致堆栈溢出。

尝试从%1中删除System.err侦听器。这将允许来自2)的内部错误浮出水面。
