rest 接口响应内容大于1kb时触发分块传输，导致报错

[imjyz]

• I have searched the issues of this repository and believe that this is not a duplicate.

Environment

• Dubbo version: 3.2.5
• Java version: 1.8

Steps to reproduce this issue

1. 使用rest协议暴露一个接口，响应内容大于 1kb
2. 服务启动后，访问该接口即可触发。

Actual Behavior

实际响应内容会追加报错信息

dubbo rest invoke Internal error, message is null ,and exception type is : class java.lang.IllegalStateException , stacktrace is:

org.apache.dubbo.rpc.protocol.rest.netty.NettyHttpResponse中通过一下方式创建outputstream

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。

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
