Subject Tomcat 7.0: compression="on" or compression="force" running on Java 1.8.0_151 causes content encoding errors in browsers
Date Thu, 26 Oct 2017 13:36:41 GMT
Hello,

We have a very stange problem. Since updating java 8 to build 151 (x86-64), 
tomcat is producing illegal compressed responses - sometimes. Firefox and Chrome 
are complaining about content encoding errors. Firefox error message is: an 
invalid or unknown form of compression was used.

Tested with tomcat 7.0.56 ant tomcat 7.0.82 on debian stretch and ubuntu artful. 
The debian system is running on openvz kernel 2.6.32-46-pve (system locale 
en_US.UTF-8). Ubuntu is running kernel 4.13.0-16 with locale de_DE.UTF-8.

Tomcat's manager,docs and demo pages are working.
A lot of pages of Psi-Probe <https://github.com/psi-probe/psi-probe> (Version 
2.3.0 and current HEAD) are failing.
Also failing is a webservice result redirected over 
org.apache.camel.component.servlet.CamelHttpTransportServlet from apache camel 2.20.

Going back to oracle jdk 1.8.0_144 or openjdk 1.8.0_141 resolves that issue.

A tcpdump of a failed Psi-Probe page is attached. My knowledge about HTTP ist 
limited. Could anyone take a look at it?


Thank You and with best regards,

Joerg
