Hi Jan,

Many thanks for the tip. We were able to figure out the problem, once we understood why the PrintWriter was getting closed.

Turns out we had a mobile detection within the JSP that was forwarding the request to another JSP page. This was happening early enough so that it was not causing issues with Jetty 9.2.x, while it did cause the issue in Jetty 9.4.x

We moved that code to a controller servlet and it seems to be working better now.

Thanks again for the timely pointer.

Pankaj,

Hhhm, looks like the PrintWriter has already been closed. Can you put a breakpoint in org.eclipse.jetty.server.ResponseWriter.close() and see who is calling it?

Also, are you using HttpServletResponseWrappers? If so, make sure that if you have overridden getWriter() that you have also overridden getOutputStream().

Hi Jan,

Thanks for taking a look at it.

I don't have an IE, but I've tried in Safari and FF and direct access to the page works okay.

I did try to put it in production briefly to test it out and got quite a few exceptions, so am thinking it's happening on direct access as well.

It's very strange. BrowserStack sends out two requests: (1) probably when the machine is starting out to cache the page, and then (2) another request to the same page.

The first one causes the exception. The second one does not. Both requests have a 200 response in the access log, but the first one has 3x the number of bytes transferred. The second one is correct.

207.254.62.90 - - [04/Sep/2017:23:52:28 +0000] "GET /pub?group=1 HTTP/1.1" 200 27859
184.169.130.92 - - [04/Sep/2017:23:52:34 +0000] "GET /pub?group=1 HTTP/1.1" 200 8585

The test site is at: https://m4s1.zeemaps.com/pub?group=1 just in case.

Full stack trace follows.

Pankaj,

Do you have the full stack trace? Also, have you tried using those versions of IE directly locally, not from within browserstack?

thanks
Jan

Hi,

We are trying to migrate a web app from Jetty 9.2 to 9.4.

Everything seems to be working okay, except for some requests from IE 11, 14, 15 we get a "Stream Closed" warning in the log for JSP files.

Here's a top level snippet of the warning:

2017-09-02 20:22:50.458:WARN:oejs.HttpChannel:qtp1076835071-12: /map
javax.servlet.ServletException: org.apache.jasper.JasperException: org.eclipse.jetty.io.RuntimeIOException: org.eclipse.jetty.io.EofException: Stream closedn.handle(HandlerCollection.java:146)

The page loads fine and the warning doesn't seem to impact the delivery of the web page.

We tried out in several browsers in browserstack, and only IE seems to be causing this.

Even more strange, browserstack running within Safari doesn't cause the warning, while running within Firefox it does.

Stumped. Would appreciate any pointers.

Thanks,

Pankaj
