NoSuchOperationError on deployment of SSB

i'm trying to deploy and run the test ejb in ./modules/j2ee/target/test-ejb.jar. after fixing the ejb-jar.xml (see bug 266) it deploys cleanly but when I bring the server up I get a org.apache.geronimo.gbean.jmx.NoSuchOperationError:

I get the same exception when I try to deploy one of my stateless session EJB's (a really simple one) but I thought that the jar in the source tree would make a better test case. Not sure if this is tragic or not but it looks kinda scary.
