   org.apache.dubbo.rpc.protocol.rest.netty.NettyHttpResponse中通过一下方式创建outputstream
   ```java
   os = new ChunkOutputStream(this, ctx, 1000);
   ```
   
   org.apache.dubbo.rpc.protocol.rest.netty.ChunkOutputStream 会分块处理长度超过1000的响应内容。
   ```java
   public void write(byte[] b, int off, int len) throws IOException {
           int dataLengthLeftToWrite = len;
           int dataToWriteOffset = off;
           int spaceLeftInCurrentChunk;
           while ((spaceLeftInCurrentChunk = buffer.maxWritableBytes()) < dataLengthLeftToWrite) {
               buffer.writeBytes(b, dataToWriteOffset, spaceLeftInCurrentChunk);
               dataToWriteOffset = dataToWriteOffset + spaceLeftInCurrentChunk;
               dataLengthLeftToWrite = dataLengthLeftToWrite - spaceLeftInCurrentChunk;
               flush();
           }
           if (dataLengthLeftToWrite > 0) {
               buffer.writeBytes(b, dataToWriteOffset, dataLengthLeftToWrite);
           }
       }
   ```
   
   org.apache.dubbo.rpc.protocol.rest.extension.resteasy.filter.ResteasyResponseContainerFilterAdapter会在 `restOutputStream(response);` 时触发异常
