java - 当异常传播到 ServerImpl.doStart() 时，如何在容器初始化期间快速失败 JBoss(即 System.exit())

Question

具体而言，请考虑以下情况:JBoss 在 ServiceMBeanSupport (rmi) 初始化期间尝试在 1099 上打开套接字，但端口 1099 已被占用。

当前的行为是异常是 system.err'd 并且 JBoss 继续初始化。随后，在应用程序运行时，jndi 查找会导致执行线程挂起——这不好，而且比失败的容器初始化更难诊断。

所以问题是，如何在初始化异常时快速失败 JBoss？

这是跟踪:

据我所知，你不能这样做，但你是对的，这样做很烦人。

如果您在 *nix 上运行它，我的建议是编写一个 bash 脚本来提前检查端口可用性，并且仅在可用时启动 JBoss。也许你可以在 Windows 上使用 cygwin 做类似的事情。
