Before submitting a PR:

• [ ] Changes must not break binary backwards compatibility. If you are unclear on how to make the change you think is needed while maintaining backward compatibility, CONTRIBUTING.md for details.
• [ ] Add JavaDocs and other comments as appropriate. Consider including links in comments to relevant documentation on https://docs.github.com/en/rest .
• [ ] Add tests that cover any added or changed code. This generally requires capturing snapshot test data. See CONTRIBUTING.md for details.
• [ ] Run mvn -D enable-ci clean install site locally. If this command doesn't succeed, your change will not pass CI.
• [ ] Push your changes to a branch other than main. You will create your PR from that branch.

When creating a PR:

• [ ] Fill in the "Description" above with clear summary of the changes. This includes:
  • [ ] If this PR fixes one or more issues, include "Fixes #" lines for each issue.
  • [ ] Provide links to relevant documentation on https://docs.github.com/en/rest where possible.
• [ ] All lines of new code should be covered by tests as reported by code coverage. Any lines that are not covered must have PR comments explaining why they cannot be covered. For example, "Reaching this particular exception is hard and is not a particular common scenario."
• [ ] Enable "Allow edits from maintainers".

@bitwiseman Can you review my changes? I know checks are breaking, but this is because I change a method signature. I don't see how this can be avoided.

P.S. I used the StackOverflow link you referenced in the issue as a source to implement the changes.

@bloslo To address API breaks, you'll need to use WithBridgeMethods annotations. They preserve binary compatibility while letting you update the source API. Usage is described in the source file and there are plenty of examples in this project.

@bitwiseman is there a chance to get this merged in?

[bitwiseman]

@Haarolean See my previous comment. There are API breaking changes that need to be addressed (using bridge methods) before this can be merged.
