java - log4j 计算器

标签 java log4j stack-overflow

<分区>

这是 stackoverflow 站点上真正的 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

最佳答案

此处缺少您的 log4j 配置文件和代码。

但最初的猜测是

1) LoggingOutputStream在代码的某处使用，像这样替换 System.err:

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

2) log4j 未正确配置并尝试将内部错误打印到 LogLog 中的 System.err .

这会创建导致堆栈溢出的循环日志记录调用。

尝试从 1) 中删除 System.err 拦截器。这将使 2) 中的内部错误浮出水面。
