launch.script can't stop app in supervisor

[tietang]

org/springframework/boot/loader/tools/launch.script

supervisor need to get APP PID that is running, but "sh spring-boot-app-exec.jar run" get two process, one is shell process, another is spring-boot-app process, but supervisor got a shell process, when executing stop command in supervisor, can't stop spring-boot-app process.

supervisor *.conf

command= sh spring-boot-app-exec.jar run

I add "exec" to "org/springframework/boot/loader/tools/launch.script" before "$command" , it works!

$command to exec $command

run() { 
  pushd "$(dirname "$jarfile")" > /dev/null
  exec $command
  result=$?
  popd
  return "$result"
}

I don't think we want to make the proposed change. Using exec significantly changes the semantics of the script as it replaces the shell with the command that's being run. For example, when run in a non-interactive shell, it will terminate when exec fails, rather than running the remainder of the script.

Why do you need to use sh spring-boot-app-exec.jar run as the command? You could make the jar itself executable and use spring-boot-app-exec.jar as run is the default action.
