title: Grails 2.4 and hibernate4 errors with run-app
body: <p>I've upgraded an app to Grails 2.4.0, and I'm using the hibernate4 plugin. When executing run-app the error examples below are generated for each domain class using the in-memory database. I've read several posts on the hibernate forums that the errors aren't serious. It's simply logging an error because the table it's trying to drop doesn't yet exist.</p>
  <blockquote>

  <p>Does anyone know how to stop the logging noise?</p>
