I use Sesame 2.3.2 with Elmo 1.5
Virtuoso drivers come from:
ftp://download.openlinksw.com/support/vos/virt_sesame2.jar
ftp://download.openlinksw.com/support/vos/virtjdbc3.jar

and Virtuoso is Open Source:
    * Version: 06.01.3127
    * Build: Jul 9 2010

I also get an error related to blank nodes (representing
rdfs:Container) not being castable into java.util.List
"Exception in thread "AWT-EventQueue-0" java.lang.ClassCastException:
_:b10149 cannot be cast to java.util.List"

Hope it helps.
