Spring Improve SimpleCommandLineArgsParser's javadoc - add other invalid example

Affects: 5.x (perhaps olders)

---

I have the following situation:

• Spring Framework: Why command line argument “--argument-name=” throws Invalid argument syntax?

I read the javadoc of the SimpleCommandLineArgsParser class

Through a comment of the post, now is clear the reason, therefore I think has sense to include a new invalid scenario:

• --foo=

If it is acceptable I would add that scenario and send a pull request. But I need your confirmation first.

Thanks

Looking at the SO, I don't think an update to the documentation is warranted for this. The Spring Boot documentation already states that command line arguments start with two dashes. If you decide to pass extra arguments with a single dash or two dots or whatever, you can't expect this to work with the same rule.
