@ww-mgr thanks for the PR. Do you mind updating the Petstore sample for Java Jersey2 API client as mentioned in the contributing guidelines?

[ww-mgr]

Sorry, I missed that part. I've updated the Petstore sample. All generated files have been changed because of the Generated annotation. It is better to commit only the relevant files next time?

[wing328]

That's ok. To me, it's fine to commit those files with the timestamps updated in the annotation only.
