Java 为什么对Grizzly HTTP服务器的POST请求主体不完整？

我正在使用Grizzly HTTP服务器（Grizzly-comet-server-2.2.1.jar）。HTTP请求由

org.glassfish.grizzly.HTTP.server.HttpHandler

的后代处理。有时（似乎是随机的）使用

Request

参数调用方法

service（Request-Request，Response-Response）

，其中content-length头的值与接收到的帖子正文的实际长度不同：

request.getInputStream().available() < request.getContentLength().

处理程序本身

public class MyHttpHandler extends HttpHandler {

    protected static Logger log = Logger.getLogger(MyHttpHandler.class);

    public void service(Request
            request, Response
            response) throws Exception {

         if (request.getInputStream().available() != request.getContentLength()) {
             log.error("broken content section: only " + request.getInputStream().available() + " of " +
                    request.getContentLength() + "bytes.");
         }
        response.setContentLength(0);
        response.getWriter().write("");
    }
}

Grizzly服务器正常。看到答案了吗

public class MyHttpHandler extends HttpHandler {

    protected static Logger log = Logger.getLogger(MyHttpHandler.class);

    public void service(Request
            request, Response
            response) throws Exception {

         if (request.getInputStream().available() != request.getContentLength()) {
             log.error("broken content section: only " + request.getInputStream().available() + " of " +
                    request.getContentLength() + "bytes.");
         }
        response.setContentLength(0);
        response.getWriter().write("");
    }
}
