I'm getting the same errors with the SVN checkout as of yesterday.
I'd really appreciate if someone could explain how the Virtualization Server is started, I can see alot of references to registry and mBeans so I am guessing it's more than just another complete tomcat instance started by a shell script? Also looking at $VIRTUAL_TOMCAT_HOME the installation contains a subset of a full tomcat install (no bin/ directory containing startup scripts). So the SVN build differs quite a bit from the Labs binary install.
