Bug ID: 62358
Summary: Stream not writable error when using HTTP2 upgrade
protocol on Firefox
Product: Tomcat 9
Version: 9.0.8
Hardware: PC
Status: NEW
Severity: minor
Priority: P2
Component: Catalina
Assignee: dev@tomcat.apache.org
Reporter: emry.eg...@calero.com
Target Milestone: -----
Created attachment 35919

Tomcat stderr log file
Current Setup (if information is necessary):
Tomcat 9.0.8
ORDS (Oracle REST Data Services) Version 18.1.1.95.1251 (ords.war file
downloadable from Oracle's website)
Firefox 59.0.3
JDK and JRE version 1.8.0_161
There are some pages in our application that when the page is accessed from
Firefox (only Firefox. Not a problem in any other browser), the page freezes.
Looking at the browser debugger, a request was sent, but no response was
received. When this situation happens, an error is logged in Tomcat's stderr
log file.
Looking at the stack that is printed in the error in the log file, one of the
lines is:
org.apache.coyote.http2.Http2UpgradeHandler.reserveWindowSize(Http2UpgradeHandler.java:733)
Our current setup in server.xml is utilizing the HTTP2 upgrade protocol.
Thinking that was related to the error, we removed that so that Tomcat was
using the HTTP 1.1 protocol again. After going back to 1.1, the problem no
longer occurs.
Attached is the log file with the generated errors. Please let me know if
there is anything more information I can provide to help troubleshoot the
issue.
