Java command line comment option

Question

It would be useful to have a java runtime option which does not do anything but only for informational purposes.

Background: We have a custom scheduler system with Web interface where we put command lines to start our jobs, and having that option would allow us to easily search by text criteria among these command lines.

So ideally this would look like

java <some_options> -XX:Comment="my comment" MyClass

Important thing, there must be a guarantee that this option will not affect the functioning of the program in any way.

The only idea I can think of is using option -D with non-existent property name. Is there any better idea?

Wouldn't it be better if your scheduler had a field for comments? — Federico klez Culloca, Nov 08 '21 at 20:33
Write your own command to launch java and record your comment; use that `my_java` instead of `java`. — Elliott Frisch, Nov 08 '21 at 20:36

I think if you need a flag to help you search your commands, you can just add a field or column to the command record which help searching. For example, Suppose your command is stored in a table Command of a database. It may look like this:

cron	command	keywords
1,3,4,7 * * * *	java Myclass1	hello world,apple
1-6 * * * *	java Myclass2	orange

I cannot change the scheduler application, but thanks anyway – ALV00 Nov 16 '21 at 22:58
