的Java客戶端的WebSockets暗流的BasicWebSocketSessionRemoteEndpoint sendBinary拋出BufferOverflowException

Question

我，從我的WebSocket客戶採取下面的代碼片段：

byte[] message = "test".getBytes(); 
session.getBasicRemote().sendBinary(ByteBuffer.wrap(message)); 

會話UndertowSession和getBasicRemote（）返回BasicWebSocketSessionRemoteEndpoint對象。

當調用sendBinary（）方法拋出BufferOverflowException以下堆棧跟蹤：

我也試着撥打sendBinary與分配的ByteBuffer：

ByteBuffer buff = ByteBuffer.allocate(message.length); 
buff.put(message); 
buff.flip(); 
this.session.getBasicRemote().sendBinary(buff); 

但得到了同樣的異常。

任何想法如何解決這個問題？

謝謝！

好了，想通了這一點：改變暗潮的web套接字緩衝區大小，以極少數的我的代碼
