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

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/c74595783a821cf43de45def094254c... 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. Sebi ps : This also affects people using the latest version of Springboot, as it uses tomcat 8.5.5
