Description

Running with JDK7, we sometimes get a null pointer when the XML spring file is loaded.
This can come from the JDK7 JAXB parser (or from the the latest Spring on JDK7)

Exception in thread "main" org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [context/james-server-context.xml]; nested exception is java.lang.NullPointerException
