[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.
