java.lang.IllegalArgumentException：utext_close失败：U_ILLEGAL_ARGUMENT_ERROR

Question

我正在Android Studio中开展一个项目。我为android做了聊天客户端。我在NetBeans IDE上创建服务器。但我在android上的聊天客户端遇到了麻烦。这是我的代码：

    class ChatUpd extends AsyncTask<Void, String, String> {
        ProgressBar progressBar;
        int count;
        protected void onPreExecute() {
            progressBar = findViewById(R.id.progressBar);
            progressBar.setMax(200);
            progressBar.setProgress(1);
            count = 0;
        }
        @Override
        protected String doInBackground(Void... voids) {
            for ( ; ; ) {
                publishProgress();
                try {
                    Thread.sleep(1);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
        @Override
        protected void onProgressUpdate(String... values) {
            count++;
            progressBar.setProgress(count);
            adapter.notifyDataSetChanged();
            if (connected == 1) {
            new Thread(new Runnable() {
                @Override
                public void run() {
                    try {
                        while (true) {
                            if (inMessage.hasNext()) {
                                String inMes = inMessage.nextLine();
                                String clientsInChat = "Clients count = ";
                                if (inMes.indexOf(clientsInChat) == 0) {
                                } else {
                                    chat.add(inMes);
                                    adapter.notifyDataSetChanged();
                                    }
                                }
                            }
                        } catch (Exception e) {
                            Log.w("Infinite loop error!", e);
                        }
                    }
                }).start();
            }
        }
        public void onPostExecute(String result) {
            Toast.makeText(getApplicationContext(),result,Toast.LENGTH_LONG).show();
        }
    }
}

这部分代码由于某种原因给我一个错误。那个错误是：

 java.lang.OutOfMemoryError: pthread_create (stack size 16384 bytes) failed: Try again

我究竟做错了什么？
