  • Integrating with Spring Flex, I defined a custom Login Command, like this. <beans:bean id="myLoginCommand" class="com.lyreco.sfm.security.CustomLoginCommand" > <beans:constructor-arg ref="_authenticationManager" /> </beans:bean> Analyzing I think it is due to this line of Code in SecurityConfigurationPostProcessor: boolean invalidateHttpSession = (Boolean) beanDefinition.getAttribute("invalidateHttpSession"); As invalidateHttpSession is not defined, it is null so casting to boolean throws NPE I get a NPE: org.springframework.beans.factory.BeanCreationException: Error creating bean with name '_messageBrokerDefaultHandlerMapping': Initialization of bean failed;
