如何使用 java 9 终止当前进程

Question

我已经尝试使用下面的代码 destroy 和 destroyForcibly -

ProcessHandle currentProcess = ProcessHandle.current();
System.out.println("current process id:"+currentProcess.getPid());
currentProcess.destroyForcibly();

但在这两种情况下都出现异常

Exception in thread "main" java.lang.IllegalStateException: destroy of current process not allowed at java.base/java.lang.ProcessHandleImpl.destroyProcess(ProcessHandleImpl.java:308) at java.base/java.lang.ProcessHandleImpl.destroyForcibly(ProcessHandleImpl.java:331) at util.CurrentProcess.main(CurrentProcess.java:18)

Answer 1

Javadoc on ProcessHandle::current 说：

Returns a ProcessHandle for the current process. The ProcessHandle cannot be used to destroy the current process, use System.exit instead.
