是否有完整的 JVM 退出代码列表 [英] Is there a complete List of JVM exit codes

问题描述

我正在寻找所有可能的 jvm 退出代码(不是 java System.exit(x))的完整列表.通过使用搜索引擎，我唯一能找到的是 SIGTERM 退出代码列表:http://journal.thobe.org/2013/02/jvms-and-kill-signals.html .我想知道未捕获的异常是否有特定的退出代码?

I am looking for a complete list of all possible jvm exit codes (not java System.exit(x)). The only thing I could find by using a search engine is a list of SIGTERM exit codes: http://journal.thobe.org/2013/02/jvms-and-kill-signals.html . I want to know if there are specific exit codes for uncatched Exceptions?

推荐答案

传递给 System.exit(x) 的参数 -> 成为 JVM 退出代码.

Argument passed to System.exit(x) -> becomes the JVM exit code.

退出代码0用于表示正常退出.唯一的肯定退出代码，用于指示特定问题.

Exit code 0 is used to indicate normal exit. Unique positive exit code to indicate specific problem.

我想知道是否有未捕获的特定退出代码例外?

没有.如果所有非守护线程正常退出(有/无异常无关紧要)，JVM以0终止.

No. If all non-daemon threads exit normally(presence/absence of exception does not matter), JVM terminates with 0.

1 到 127 之间的退出代码是用于指示 JVM 中的错误的特定代码.例如jdk/jre 版本不匹配、内存配置/命令行选项不正确等

Exit code between 1 and 127 are specific codes used to indicate error in JVM. e.g. mismatched jdk/jre versions, incorrect memory configuration/command-line options, etc.

JVM 因特定信号而退出将是

JVM exit due to specific signal would be

128+信号标识

可以使用kill -l
