Migrating JIRA 6 custom servlet filter to JIRA 7

[SéverineC]

Hi,

We are migrating our JIRA server 6.4.5 to JIRA Software (Server) 7.3.8 right now and we are encountering a problem with one of our custom plugin.

It's a servlet filter that we have developped to interface with our CAS SSO (not for login/logout, that's another one wich extends JIRASecurityFilter and works fine) and in the logs, we have an exception that says that our class cannot be cast to javax.servlet.Filter (java.lang.ClassCastException).

I have modified the pom.xml (see below) to use the latest version of JIRA and the sal plugin and also modified it to use Java 1.8 for compiling. And yet it seems to not be enough.

When I look at the dependancies recovered, I see that we use javax-servlet-3.0.1and servlet-api.2.0.1 so I assume the problem is from there, as we moved from tomcat 7 to 8 but I can't figure out how to solve it.

Does anyone have any idea ?

Thanks !
