Java - 无法从 InputStream 读取，直到 OutputStream 关​​闭

Question

我正在尝试读取和写入 bash/cmd。我正在使用流程构建器启动流程。 第一次读取和写入命令行就完美无缺。但是当我向命令行写入内容时，在关闭缓冲编写器之前我无法从 InputStream 中读取。当我关闭缓冲写入器时，我可以再次从命令行读取。 当我这样做时，outputStream 和 inputStream 之间是否存在冲突：

Thread thread = new Thread() {
        public void run()
        {
            try
            {
                ProcessBuilder processBuilder = new ProcessBuilder("bash", "-c", "jdb" + path);
                processBuilder.redirectErrorStream(true);
                Process process = processBuilder.start();
                BufferedReader bufferedReaderInput = new BufferedReader(new InputStreamReader(process.getInputStream()));
                BufferedReader bufferedReaderError = new BufferedReader(new InputStreamReader(process.getErrorStream()));
                BufferedWriter bufferedWriter = new BufferedWriter(new OutputStreamWriter(process.getOutputStream()));
                String currentLine = "";
                while ((currentLine = bufferedReaderInput.readLine()) != null)
                {
                    bufferedWriter.write("hello");
                    bufferedWriter.flush();
                    //If I close the bufferedWriter here, I can read again from the bufferedReader.
                }
                while ((currentLine = bufferedReaderError.readLine()) != null)
                {
                    consoleWindow.appendText(currentLine);
                }
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
        }
    };
    thread.start();

尝试更改：

bufferedWriter.write("hello");

至：

bufferedWriter.write("hello\n");

没有 '\n' 就像在 jdb 中输入 "hello" 但不按回车键。
