I was able to fix this issue in my environment but I'm not 100% sure why. Basically all I did was to remove the hibernate jar out of the WEB-INF/lib but made sure it was still part of the projects build path.
Contents of WEB-INF/lib appengine-api-1.0-sdk-1.6.0.jar appengine-api-labs-1.6.0.jar appengine-jsr107cache-1.6.0.jar apps-marketplace.jar datanucleus-appengine-1.0.10.final.jar datanucleus-core-1.1.5.jar datanucleus-jpa-1.1.5.jar geronimo-jpa_3.0_spec-1.1.1.jar geronimo-jta_1.1_spec-1.1.1.jar gwt-servlet-deps.jar gwt-servlet.jar jdo2-api-2.3-eb.jar jsr107cache-1.1.jar objectify-3.1.jar requestfactory-apt.jar requestfactory-server.jar slf4j-api-1.6.1.jar slf4j-log4j12-1.6.1.jar validation-api-1.0.0.GA.jar I hope this helps.
