I came back this morning, and rebuilt the project. The verifier error has disappeared, though I haven't changed the code. If I have additional information, I'll come back and post. Seems to be an intermittent problem.
I ran into the same problem. I fixed errors that caused the verifier warnings, and after redeploying the bean, the same errors keep popping up. I've run the verifier outside of jboss and it succeeds. However, if i deploy the bean within jboss, the verifier fails. It probably has to do with the tmp directory used to cache deployed beans, but I can't seem to work out how to fix it. If you have any suggestions, please let me know. Thanks.
