A DESCRIPTION OF THE PROBLEM :
Swing Frame using nio read spring jstack file（from linux）using String.replaceAll get not expected result.

code part

            // get nid
            Matcher nidMatcher = Pattern.compile("nid=([^\\s,]+)").matcher(line);
            if (nidMatcher.find()) {
                dto.setNid(nidMatcher.group(1));
            }
                    String statePre = line.replaceAll(".*" + dto.getNid(), "");
                    System.out.println("111 "+statePre);
                    if (Objects.nonNull(dto.getStackPointer())){
                        String stateSecond = statePre.replaceAll(dto.getStackPointer(), "");
                        System.out.println("222 " + stateSecond);
                        String state = stateSecond.replace("\\[\\]", "");
                        System.out.println("333 " + state);
                        dto.setState(state);
                    } else {
                        dto.setState(statePre);
                    }
                    System.out.println(line);

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run an spring boot app in linux
jstack -l <pid> > stack.txt

in windows write swing app using nio read file

        try (BufferedReader br = Files.newBufferedReader(file)) {
            br.lines().forEach(line -> {
                if (line.matches(BusinessConstants.THREAD_NAME_INFO_REGEX)) {
                    threadInfo(line, countMap, jStackThreadLineDTOS);
                }
            });
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
