我在 Eclipse RAP（Rich Ajax Platform 1.3.2）和 Java 1.5 中使用 jetty 6.1.23。我正在向浏览器发送 PNG 图像。这些是导致麻烦的代码片段：
服务器端：
response.setContentType(application.getMimeType(".png"));
response.setContentLength(outputSize);
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);
response.setHeader("Pragma", "no-cache");
response.setDateHeader("Max-Age", 0);
ServletOutputStream servletoutputstream = response.getOutputStream();
servletoutputstream.write(imageBytes); // this throws EofException
servletoutputstream.flush();
客户端：
<img src="path to the servlet that is loading the image">
奇怪的是，这个问题并非一直都在发生。在我们投入生产后，它会间歇性地发生。我们的测试环境没有问题。生产环境和我们的测试环境唯一的区别是，在生产环境中，用户离我们的服务器很远，而在测试环境中，他们非常接近。
抛出异常时，客户端浏览器端根本不会显示图像！到底是怎么回事？我能做些什么来修复它或至少有一个解决方法？
这是完整的异常跟踪（我突出显示了关键异常）：
