GHRepository#getIssue takes id as an int. Same with getPullRequest.

GHIssue and GHPullRequest which extend GHObject returns a long for an id.

To call either, with the original object requires you to downcast.

			if (issue) {
				final GHIssue issue = repository.getIssue((int) item.getId());
			} else {
				final GHPullRequest pullRequest = repository.getPullRequest((int) item.getId());
			}

It seems to me both should be updated to be a long to make everything consistent and not require down casting.
