[drools-spring] KnowledgeSessionDefinitionParser generates nullpointerexception on parsing spring xml file due to missing class attribute on bean ------------------------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-2689 URL: https://jira.jboss.org/browse/JBRULES-2689 Project: Drools Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 5.1.0.FINAL Reporter: David Coleman Assignee: Mark Proctor Priority: Minor The error below is generated on application load when a spring bean does not specify the class attribute. Spring beans do not need to specify the class attribute as it can use the attribute parent to inherit other spring beans. Caused by: java.lang.NullPointerException at org.drools.container.spring.namespace.KnowledgeSessionDefinitionParser.parseInternal(KnowledgeSessionDefinitionParser.java:287) at org.springframework.beans.factory.xml.AbstractBeanDefinitionParser.parse(AbstractBeanDefinitionParser.java:59) at org.springframework.beans.factory.xml.NamespaceHandlerSupport.parse(NamespaceHandlerSupport.java:73) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1335) at org.springframework.beans.factory.xml.BeanDefinitionParserDelegate.parseCustomElement(BeanDefinitionParserDelegate.java:1325) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.parseBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:136) at org.springframework.beans.factory.xml.DefaultBeanDefinitionDocumentReader.registerBeanDefinitions(DefaultBeanDefinitionDocumentReader.java:93) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.registerBeanDefinitions(XmlBeanDefinitionReader.java:493) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:390) The equals comparison on 287 should be reversed to avoidthe null pointer exception but it should also take the class of the parent into account if it has been defined. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
