createCommitStatus method return status success but the update is not happening in GITHUB

[bostsnow]

Description
We are using the version 1.307 and we call the createCommitStatus like below.

GHRepository repository = gitHub.getRepository(
        SLASH_JOINER.join(request.getOrg(), request.getRepo())
      );

String headSha = repository
        .getPullRequest(request.getPullNumber())
        .getHead()
        .getSha();

GHCommitStatus commitStatus = repository.createCommitStatus(
          headSha,
          GHCommitState.SUCCESS,
          someUrl,
          someDescription,
          context()
        );

The response commitStatus status is 'SUCCESS' but Github is still not updated.
What really can go wrong here ?

Note: Its not consistent, out of 10 call, 1 update is not happening.

Additional Detail
On each commit we re-evaluate the logic and call the createCommitStatus.

Is the update actually never happening, or is if you check again a couple seconds later has the update gone through? It is possible this is call the case some delay before the result change is visible?
