Buggy source:
private void initializeProcess(Path terminalPath) throws Exception {
  String os=System.getProperty("String_Node_Str").toLowerCase();
  String[] commands;
  if (os.contains("String_Node_Str")) {
    commands=editorConfigBean.getTerminalWinCommand().split("String_Node_Str");
  }
 else {
    commands=editorConfigBean.getTerminalNixCommand().split("String_Node_Str");
  }
  ProcessBuilder processBuilder=new ProcessBuilder(commands);
  processBuilder.redirectError(ProcessBuilder.Redirect.PIPE);
  processBuilder.redirectInput(ProcessBuilder.Redirect.PIPE);
  processBuilder.redirectOutput(ProcessBuilder.Redirect.PIPE);
  processBuilder.directory(directoryService.workingDirectory().toFile());
  Optional.ofNullable(terminalPath).filter(Files::exists).map(Path::toFile).ifPresent(processBuilder::directory);
  this.process=processBuilder.start();
  Charset charset=Charset.forName(editorConfigBean.getTerminalCharset());
  this.inputStream=process.getInputStream();
  this.inputStreamReader=new InputStreamReader(inputStream,charset);
  this.inputReader=new BufferedReader(inputStreamReader);
  this.errorStream=process.getErrorStream();
  this.errorStreamReader=new InputStreamReader(errorStream,charset);
  this.errorReader=new BufferedReader(errorStreamReader);
  this.outputStream=process.getOutputStream();
  this.outputStreamWriter=new OutputStreamWriter(outputStream,charset);
  this.outputWriter=new BufferedWriter(outputStreamWriter);
  threadService.start(() -> {
    inputReader.lines().forEach(this::print);
  }
);
  threadService.start(() -> {
    errorReader.lines().forEach(this::print);
  }
);
  focusCommandInput();
  process.waitFor();
}

Fixed version (ground truth):
private void initializeProcess(Path terminalPath) throws Exception {
  String[] commands;
  if (OSHelper.isWindows()) {
    commands=editorConfigBean.getTerminalWinCommand().split("String_Node_Str");
  }
 else {
    commands=editorConfigBean.getTerminalNixCommand().split("String_Node_Str");
  }
  ProcessBuilder processBuilder=new ProcessBuilder(commands);
  processBuilder.redirectError(ProcessBuilder.Redirect.PIPE);
  processBuilder.redirectInput(ProcessBuilder.Redirect.PIPE);
  processBuilder.redirectOutput(ProcessBuilder.Redirect.PIPE);
  processBuilder.directory(directoryService.workingDirectory().toFile());
  Optional.ofNullable(terminalPath).filter(Files::exists).map(Path::toFile).ifPresent(processBuilder::directory);
  this.process=processBuilder.start();
  Charset charset=Charset.forName(editorConfigBean.getTerminalCharset());
  this.inputStream=process.getInputStream();
  this.inputStreamReader=new InputStreamReader(inputStream,charset);
  this.inputReader=new BufferedReader(inputStreamReader);
  this.errorStream=process.getErrorStream();
  this.errorStreamReader=new InputStreamReader(errorStream,charset);
  this.errorReader=new BufferedReader(errorStreamReader);
  this.outputStream=process.getOutputStream();
  this.outputStreamWriter=new OutputStreamWriter(outputStream,charset);
  this.outputWriter=new BufferedWriter(outputStreamWriter);
  threadService.start(() -> {
    inputReader.lines().forEach(this::print);
  }

  threadService.start(() -> {
    errorReader.lines().forEach(this::print);
  }
);
  focusCommandInput();
  process.waitFor();
}
