[Building Sakai] JForum ClassCastException

[Curtis Van-Osch]

Thanks Murthy, your suggestion helped us figure this out.

The compile is fine, but we realised that etudes-jforum-api-x.jar was 
present in three places:

  * webapps/etudes-jforum-tool/WEB-INF/lib
  * components/etudes-jforum-pack/WEB-INF/lib
  * shared/lib

Same thing for etudes-util-api-x.jar.  By adding <scope>provided</scope> 
to the dependencies in the pom.xml files for jforum-impl and jforum-tool 
(and etudes-util), we were able to eliminate the problem (leaving the 
apis only in shared/lib).

Last question: is there a version of JForum (and Etudes Util) that we 
should be running with Sakai 2.9.1?  We just kept our old 2.8.1 version, 
but I noticed svn has a 2.9 tag.  Would that possibly work better for 
us?  Does it need the latest etudes-util (1.0.20 tag I assume)?

Thanks again!
