when I see:

Import order: java, org, com, gobblin.

here - https://gobblin.apache.org/docs/developer-guide/CodingStyle/

I presumed javax would follow java, not pop up between com and gobblin. are you sure this is supposed to move here?

I do not do any import changes manually, intelliJ does it, hopefully based on the provided codestyle

There are many non-gaas callers to this method with Optional parameter, which may be providing parameter that is truly optional.
