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

AD_LB (Jira)

     [ https://issues.apache.org/jira/browse/DAEMON-295?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mladen Turk resolved DAEMON-295.
--------------------------------

    Resolution: Not A Problem

Check optionString in JNI_CreateJavaVM
http://docs.oracle.com/javase/7/docs/technotes/guides/jni/spec/invocation.html

This is our exit hook, so it just happens it is shown as cmdline argument.

>                 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? I even checked the Options key in the registry and exit is nowhere to be seen.
> 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 ...
