[keycloak-dev] Tomcat 8 Adapter breaks with Tomcat 8.5.5

[Sebastien Blanc]

Tomcat 8.5.5 that was released last month doesn't work with the KC Tomcat
Adapter.

This is because of this bug that has been fixed on their side :
https://bz.apache.org/bugzilla/show_bug.cgi?id=59823 and their pretty
"breaking-change" fix :
https://github.com/apache/tomcat85/commit/c74595783a821cf43de45def094254c673298e73?diff=split

I created a ticket , https://issues.jboss.org/browse/KEYCLOAK-3669 , that
describes the problem and the possible fix.

But the question is : this fix will only be valid (and possible to compile)
for version of Tomcat > 8.5.5 (including 9). Does that mean we need to
create a new Adapter just for this version ?

 I'm not sure there is another solution.

ps : This also affects people using the latest version of Springboot, as it
uses tomcat 8.5.5
