-----------------------------
Resolution: Not A Problem
> Exception starting filter struts2 java.lang.IncompatibleClassChangeError:
> Implementing class
> ---------------------------------------------------------------------------------------------
>
> Key: WW-4659
> URL: https://issues.apache.org/jira/browse/WW-4659
> Project: Struts 2
> Issue Type: Bug
> Components: Dispatch Filter
> Affects Versions: 2.3.28
> Environment: Ubuntu 16.04 LTS, JDK 7, Tomcat 8
> Reporter: Zack Macomber
> Priority: Blocker
> Fix For: 2.3.31
>
>
> My code compiles fine and my app deploys to Tomcat 8 but I'm getting the
> following error in my Tomcat localhost log when the app attempts to start.
> Any ideas on how to resolve this (or even how to get further debug info for
> where the issue is)?
> I have enabled FINE logging on the localhost log and found several other
> filters starting with no exceptions (see below updated log output). Why is
> the struts2 filter specifically having issues and all of these other filters
> aren't?
> Also as a test, I commented out the struts2 filter
> (org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter for
> me) and the application installs and starts with no issues. So, the problem
> is certainly localized to the struts2 filter.
> from my tomcat localhost log...
