I'm not sure if this is the right forum for our problem but here it is anyway:
We're using JBoss 4.2.2GA in a clustered environment. We use SEAM 2.0.0. Everything works more or less fine, but when we ran the automated integration tests, the microkernel spat this out:
java.lang.annotation.AnnotationFormatError: Invalid default: public abstract java.lang.Class org.jboss.annotation.ejb.Clustered.loadBalancePolicy()
Are you using the all config? How are you packaging things? The load balance policy classes should already be on the classpath; don't see why you'd need to add them.
The org.jboss.cache.eviction.EvictionPolicyConfig class was removed in JBoss Cache 2.0. But AS 4.2.2 runs with JBC 1.4.1. Are you packaging JBC 2.x in your deployment?
