EJB3PostLoadEventListener, as created by EventListenerConfigurator, throws NullPointerException. ------------------------------------------------------------------------------------------------ Key: HHH-5703 URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5703 Project: Hibernate Core Issue Type: Bug Components: core Affects Versions: 3.5.6 Reporter: Eduardo Born EJB3PostLoadEventListener is created by EventListenerConfigurator with its default constructor: listenerConfig.setPostLoadEventListeners( new PostLoadEventListener[] { new EJB3PostLoadEventListener(), new DefaultPostLoadEventListener() } ); The problem is that it has a callbackHandler field called which remains null, and there is no check in the postLoad method before invoking callbackHandler.postLoad( entity );. This causes a NullPointerException to be thrown there in a few situations. The fix is simple. H+In the EJB3PostLoadEventListener's postLoad() method, replace: public void onPostLoad(PostLoadEvent event) { Object entity = event.getEntity(); callbackHandler.postLoad( entity ); } by: public void onPostLoad(PostLoadEvent event) { if (callbackHandler == null) return; Object entity = event.getEntity(); callbackHandler.postLoad( entity ); } This would prevent the NullPointerException to be thrown when there is no callbackHandler. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://opensource.atlassian.com/projects/hibernate/secure/Administrators.... - For more information on JIRA, see: http://www.atlassian.com/software/jira
