[jira] [Created] (DAEMON-295) Mysterious JVM argument: exit

AD_LB (Jira)
Patrick McCarty created DAEMON-295:
--------------------------------------

             Summary: Mysterious JVM argument: exit
                 Key: DAEMON-295
                 URL: https://issues.apache.org/jira/browse/DAEMON-295
             Project: Commons Daemon
          Issue Type: Bug
          Components: Procrun
    Affects Versions: 1.0.15
         Environment: jvm mode using JDK7 server JVM on Windows
            Reporter: Patrick McCarty
            Priority: Trivial


I have a Windows service configured to use --StartMode=jvm. I noticed an unexplained JVM argument 'exit' when my service prints out the active JVM arguments at startup using the java code:
System.out.println("[Begin JVM arguments]");
for (final String jvmArg : ManagementFactory.getRuntimeMXBean().getInputArguments())
{
    System.out.println(jvmarg);
}
System.out.println("[End JVM arguments]");

For example:
[Begin JVM arguments]
-Xrs
-XX:+UseG1GC
exit
-Xms100m
-Xmx1024m
[End JVM arguments]

The arguments listed before 'exit' are those that I configured using --JvmOptions=-Xrs;-XX:+UseG1GC. The arguments listed after 'exit' were added by procrun itself based on the --JvmMs and --JvmMx arguments that I specified (if not specified, exit will be the last argument). But where did exit come from? Why is it added as a JVM argument?

Although I have not noticed any ill effects, this seems like a bug to me as I don't believe exit was added intentionally. The same behavior is observed whether run as a procrun service, or using the procrun console mode, but not when running normally using java -server -Xrs -XX:+UseG1GC -jar ...
