如果Tomcat服务器显示"Client Aborted",并且客户端显示"Premature EOF",那么谁是对的？

Question

我有一个Tomcat服务器通过http将数据流传输到Java客户端.它将字节从文件复制到servlet中的HTTPServletResponse的输出流.

客户端使用HttpURLConnection连接和读取数据.

有时一切都很好,有时候客户端和服务器都会抛出异常.
客户说有一个"早产EOF".
服务器声称"ClientAbortException".

不仅仅是上述可能之一吗？

客户:

java.io.IOException: Premature EOF
       at sun.net.www.http.ChunkedInputStream.fastRead(ChunkedInputStream.java:234)
       at sun.net.www.http.ChunkedInputStream.read(ChunkedInputStream.java:662)
       at java.io.FilterInputStream.read(FilterInputStream.java:116)

       at sun.net.www.protocol.http.HttpURLConnection$HttpInputStream.read(HttpURLConnection.java:2664)  

服务器:

它们不是相互排斥的.

如果套接字意外关闭,可能会发生这种情况.例如,考虑一下如果防火墙刚刚终止套接字会发生什么.从服务器的角度来看,当它尝试写入数据时,套接字将显示为关闭状态,并且将触发ClientAbortException.从客户端的角度来看,下一次读取字节会失败,从而导致过早结束异常.
