[Building Sakai] Jforum in Sakai 10

[Kusnetz, Jeremy]

Has anyone gotten Jforum working in Sakai 10?  Etudes has Melete working for Sakai 10:
http://etudes.org/help/developers/melete/download/
which uses etudes-util 1.0.25

But for Jforum it looks like the last version was for Sakai 2.9 using etudes-util 1.0.17
http://etudes.org/help/developers/jforum/download/

I was able to get Jforum to build with etudes-util 1.0.25 (we are also running Melete), but when I actually hit the tool in Sakai I get the following exceptions:
