Buggy source:
public String[] tokenize(String src){
  List<String> tokens=new ArrayList<>();
  int index=0;
  while (index < src.length()) {
    final int contextStart=index;
    ITokenizingContext ctx=(relStart,relEnd) -> {
      int start=contextStart + relStart;
      int end=contextStart + relEnd;
      int stringEnd=src.length();
      String gotten=src.substring(start,Math.min(end,stringEnd));
      while (gotten.length() < end - start) {
        gotten+=END_OF_LINE;
      }
      return gotten;
    }
;
    boolean consumed=false;
    for (    ITokenizerGobbler token : tokenizers) {
      TokenResult res=token.tokenizePart(ctx);
      if (res == ResultSpecific.IGNORE)       continue;

      }

        int discardLength=((ResultDiscard)res).length;
        index+=discardLength;

Fixed version (ground truth):

  List<String> tokens=new ArrayList<>();
  int index=0;
  while (index < src.length()) {
    final int contextStart=index;
    ITokenizingContext ctx=(relStart,relEnd) -> {
      int start=contextStart + relStart;
      int end=contextStart + relEnd;
      int stringEnd=src.length();
      String gotten=src.substring(start,Math.min(end,stringEnd));
      while (gotten.length() < end - start) {
        gotten+=END_OF_LINE;
      }
      return gotten;
    }
;
    boolean consumed=false;
    for (    ITokenizerGobbler token : tokenizers) {
      TokenResult res=token.tokenizePart(ctx);
      if (res == ResultSpecific.IGNORE)       continue;
      if (res == ResultSpecific.INVALID) {
        throw new InputMismatchException("String_Node_Str" + ctx.get(10).replace("String_Node_Str","String_Node_Str") + "String_Node_Str");
      }
      if (res instanceof ResultInvalid) {
        throw new InputMismatchException("String_Node_Str" + ctx.get(((ResultInvalid)res).length).replace("String_Node_Str","String_Node_Str") + "String_Node_Str");
      }
      if (res instanceof ResultDiscard) {
        int discardLength=((ResultDiscard)res).length;
        index+=discardLength;
        consumed=true;
        break;
      }
      if (res instanceof ResultConsume) {
        int consumedLength=((ResultConsume)res).length;
        String at=ctx.get(consumedLength);
        tokens.add(at);
        index+=consumedLength;
        consumed=true;
        break;

    }
