何时捕获 java.lang.Error? [英] When to catch java.lang.Error?

问题描述

在什么情况下应该在应用程序上捕获java.lang.Error?

In what situations should one catch java.lang.Error on an application?

推荐答案

一般情况下，从不.

但是，有时您需要捕获特定错误.

However, sometimes you need to catch specific errors.

如果您正在编写类似于框架的代码(加载第 3 方类)，最好捕获 LinkageError(未找到类定义、不满意的链接、不兼容的类更改).

If you're writing framework-ish code (loading 3rd party classes), it might be wise to catch LinkageError (no class def found, unsatisfied link, incompatible class change).

我还看到一些愚蠢的 3rd-party 代码抛出 Error 的子类，所以你也必须处理这些.

I've also seen some stupid 3rd-party code throwing subclasses of Error, so you'll have to handle those as well.

顺便说一句，我不确定是否无法从 OutOfMemoryError 中恢复.

By the way, I'm not sure it isn't possible to recover from OutOfMemoryError.
