Stuart McCulloch commented on MNG-5620:
---------------------------------------
I listed the various solutions in http://markmail.org/message/deh5q7tk5fwa35yo
(ie. narrow the export, widen the export, or remove the export) along with what
it does and why you might want to keep it exported:
http://markmail.org/message/5ba2hz7unavrlkmt - and last I heard Igor wanted it
kept exported: http://markmail.org/message/xvq4ku32cvxcxsai
But it's up to you whether to export it or not, if you don't export it then it
just disables that feature.

> How to reproduce:
> 1) git clone https://github.com/apache/wicket.git
> 2) mvn install (just to have all dependencies)
> 3) cd wicket-examples
> 4) mvn jetty:run (fails with 3.1.0+)
