A much shorter and clean solution can be done via the "log" command that JGit provides:

    Repository repository = new FileRepository("pathToRepo/.git");
    logs = new Git(repository).log()
            .add(repository.resolve("remotes/origin/testbranch"))
            .call();
    count = 0;
    for (RevCommit rev : logs) {
        System.out.println("Commit: " + rev /* + ", name: " + rev.getName() + ", id: " + rev.getId().getName() */);
        count++;
    }
    System.out.println("Had " + count + " commits overall on test-branch");
