I used org.glassfish.jaxb:jaxb-runtime:4.0.2 JaxbEntityMappings obj = ... jaxbContext = JAXBContext.newInstance(JaxbEntityMappings.class); final Marshaller marshaller = jaxbContext.createMarshaller(); marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, Boolean.TRUE); marshaller.marshal(obj, System.out); Got this error: noformat Caused by: java.lang.NullPointerException at org.hibernate.boot.jaxb.mapping.marshall.AccessTypeMarshalling.toXml(AccessTypeMarshalling.java:22) at org.hibernate.boot.jaxb.mapping.Adapter1.marshal(Adapter1.java:17) at org.hibernate.boot.jaxb.mapping.Adapter1.marshal(Adapter1.java:7) at org.glassfish.jaxb.runtime.v2.runtime.reflect.AdaptedAccessor.get(AdaptedAccessor.java:46) ... 23 more noformat Same problem with the class FetchTypeMarshalling I think a null check is needed in toXml() ( https://hibernate.atlassian.net/browse/HHH-16373#add-comment?atlOrigin=ey... ) Add Comment ( https://hibernate.atlassian.net/browse/HHH-16373#add-comment?atlOrigin=ey... ) Get Jira notifications on your phone!
