Mike shows these NoClassDefFoundErrors during deployment of EJB3 applications:

2009-10-22 09:29:31,049 DEBUG [org.jboss.ejb3.deployers.Ejb3Deployer] (RMI TCP Connection(5)-127.0.0.1) Error during deploy: vfszip:/home/hudson/workspace/EJB3_Plugin_Integration_TestSuite_AS_Latest_Targeted/trunk/testsuite/target/test-lib/clusteredentity-test.jar/
org.jboss.deployers.spi.DeploymentException: Error deploying clusteredentity-test.jar: org/jboss/ejb3/jpa/integration/AbstractEntityManagerDelegator
at org.jboss.ejb3.deployers.Ejb3Deployer.deploy(Ejb3Deployer.java:196)
at org.jboss.ejb3.deployers.Ejb3Deployer.deploy(Ejb3Deployer.java:99)

Appropriately package these JPA integration jars into the AS (both from EJB3 plugin and from the component-matrix of AS)
