After not much help from the mailing list, I updated to Grails RC1.0 without success. Adding the newest Hibernate JARs and Annotations JARs to the grails/lib directory solved my issue though.

The problem usually comes down to the "asm.jar" file, which is normally included in both the Hibernate library and the Spring 2.0 library. Unfortunately, each includes a different version, and the conflict breaks the application. I do remember seeing a post on one of email lists you mentioned about a similar conflict. Grails is built on top of both Spring and Hibernate, so maybe that's not surprising. By the way, if you can't get into the email lists directly, both are archived at Nabble: http://www.nabble.com/codehaus---Groovy-f11866.html for Groovy, and http://www.nabble.com/grails---user-f11861.html for Grails.
