Hi all,
We are encountering a weird but frequent exception when users try to
access AVI video playback on IE11.
My analysis is that it's a bad behavior of Tomcat when using
HttpServletResponseWrapper.
I did not want to immediately create a bug report, first because you
might have other insight on the subject, and also because the bug
affects all tomcat version, thus I wanted to be sure on the appropriate
way to report. Indeed the bug report page
(https://tomcat.apache.org/bugreport.html) does not explain what to do
if bugs affect several version of Tomcat. Only enter bug for the latest
version ? Enter bug serval time ? Or maybe there is a way to select
multiple product at once ?
I have setup a very simple reproduction webapp (2 nearly empty class,
one html, one video) that can be downloaded here :
https://www.dropbox.com/s/q61obn8381hugug/test.war?dl=0 (204.72 KB)
This webapp is configured with a simple servlet filter, doing nothing
special but wrapping the response using a simple
HttpServletResponseWrapper (not doing anything at all) and logging
request information on exception.
To help demonstrate the cause of the problem, the filter expose an init
parameter "wrap-response" in web.xml which quickly allows the webapp to
be tested with 2 behavior : response wrapped (to exhibit the bug) or not
(to behave properly).
The home page contains a video player with a very small AVI file.
The reproduction steps :
* Start Tomcat (any version) with the webapp above
* Access the index page using IE 11 on Windows 7 (very important :
clear browser cache between each test)
--> The exception at the end of this message occurs.
* Edit web.xml, set "wrap-response" init parameter to false
* Repeat the test with IE (don't forget to clear cache!)
--> No exception.
The problem may be workaround by modifying Tomcat's web.xml by disabling
Accept-Ranges support.
<init-param>
<param-name>useAcceptRanges</param-name>
<param-value>false</param-value>
</init-param>
Because the ClientAbortException/IOException does not occurs if the
response is not wrapped, and does not occurs either if acceptRange is
disabled, it really make me think that is a bug in Tomcat (and not a
behavior of the client contrary to what ClientAbortException implies).
Bug verified to exist in all following version (with a default install)
(using JDK 1.8.0_102-b14 on Win7 SP1):
Apache Tomcat/7.0.70
Apache Tomcat/8.0.36
Apache Tomcat/8.5.4
Apache Tomcat/9.0.0.M9
** Should I fill the bug report? and if so, on which product should I
report the bug ? **
Thanks for your help,
Olivier
