Buggy source:
@Override public Commit getCommit(String id){
  try {
    Git git=Git.open(new File(path));
    Repository repo=git.getRepository();
    Iterable<RevCommit> commits=git.log().add(repo.resolve(id)).call();
    Commit theCommit=null;
    for (    RevCommit jgitCommit : commits) {
      Committer committer=new Committer(jgitCommit.getAuthorIdent().getName(),jgitCommit.getAuthorIdent().getEmailAddress());
      String msg=jgitCommit.getFullMessage().trim();
      String hash=jgitCommit.getName().toString();
      long epoch=jgitCommit.getCommitTime();
      String parent=(jgitCommit.getParentCount() > 0) ? jgitCommit.getParent(0).getName().toString() : "String_Node_Str";
      GregorianCalendar date=new GregorianCalendar();
      date.setTime(new Date(epoch * 1000L));
      theCommit=new Commit(hash,committer,date,msg,parent);

Fixed version (ground truth):
@Override public Commit getCommit(String id){
  try {
    Git git=Git.open(new File(path));
    Repository repo=git.getRepository();
    Iterable<RevCommit> commits=git.log().add(repo.resolve(id)).call();
    Commit theCommit=null;
    for (    RevCommit jgitCommit : commits) {
      Committer committer=new Committer(jgitCommit.getAuthorIdent().getName(),jgitCommit.getAuthorIdent().getEmailAddress());
      String msg=jgitCommit.getFullMessage().trim();
      String hash=jgitCommit.getName().toString();
      long epoch=jgitCommit.getCommitTime();
      String parent=(jgitCommit.getParentCount() > 0) ? jgitCommit.getParent(0).getName().toString() : "String_Node_Str";
      GregorianCalendar date=new GregorianCalendar();
      date.setTime(new Date(epoch * 1000L));
      theCommit=new Commit(hash,committer,date,msg,parent);
      for (      DiffEntry diff : diffsForTheCommit(repo,jgitCommit)) {
        ModificationType change=Enum.valueOf(ModificationType.class,diff.getChangeType().toString());
        String oldPath=diff.getOldPath();
        String newPath=diff.getNewPath();
        String diffText="String_Node_Str";
        String sc="String_Node_Str";
        if (diff.getChangeType() != ChangeType.DELETE) {
          diffText=getDiffText(repo,diff);
          sc=getSourceCode(repo,diff);
        }
        theCommit.addModification(oldPath,newPath,change,diffText,sc);
