javajvm-arguments

Is the syntax --add-opens=... (with equals sign) officially supported?

The docs show a space:

--add-opens module/package=target-module

But I also see variations without space:

--add-opens=module/package=target-module

I couldn't find any official docs showing the equals sign. I'm worried that this could be JVM-vendor-specific.

Solution

  • As mentioned in the comments by user85421, the documentation of the java command you link, under Overview of Java Options, explicitly says:

    Note: To specify an argument for a long option, you can use either --name=value or --name value.

    In other words, yes, either syntax is officially supported.
