title: Hibernate - java.lang.NoClassDefFoundError
body: <p>Implementing a web service using Hiberate for persistence layer.  Works great, with no errors.  However, when I write a unit test to access the Dao an encounter this error when getting an instance of the ServiceRegistry:</p>
  
  <pre><code>ServiceRegistry sr = new ServiceRegistryBuilder().applySettings(
                      configuration.getProperties()).buildServiceRegistry();
  </code></pre>
  
  <p>Full stack trace:</p>

  <p>I have verified that the class does not exist in the classpath.  To correct that I need to get an older version of usertype.spi. </p>
  
  <p>Question is, why would it try to utilize an older class file when unit testing but work absolutely fine when running the service in a container?  Has anyone seen this issue before?</p>
