There would be no helpful message then, the `jspawnhelper` would just exit on argument count check. So I suggest we polish the failure messages a bit: always report version at `shutItDown`, and report more verbose failure messages too. See: [jspawnhelper-messages-1.patch](https://github.com/openjdk/jdk/files/14586196/jspawnhelper-messages-1.patch) Older JDK invoking new jspawnhelper would then fail like: % build/macosx-aarch64-server-fastdebug/images/jdk/lib/jspawnhelper 1:1:1 Incorrect number of arguments: 2 jspawnhelper version 23-internal-adhoc.shipilev.shipilev-jdk This command is not for general use and should only be run as the result of a call to ProcessBuilder.start() or Runtime.exec() in a java application ------------- PR Comment: https://git.openjdk.org/jdk/pull/18204#issuecomment-1994051562
