Error creating bean with name '_muleNotificationManager'

[J Enthusiast]

I am currently trying to upgrade my existing spring version to 4.x and I get the following error at the server startup. No sure what exactly I am missing. Appreciate any help here.

level=WARN class=MuleArtifactContext Exception encountered during context initialization - cancelling refresh attempt

org.springframework.beans.factory.BeanCreationException: Error creating bean with name '_muleNotificationManager': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'mvcUriComponentsContributor': Cannot create inner bean '(inner bean)#64c66745' of type [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter] while setting bean property 'handlerAdapter'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name '(inner bean)#64c66745': Invocation of init method failed; nested exception is java.lang.IllegalStateException: ApplicationObjectSupport instance [org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter@1431724e] does not run in an ApplicationContext

Thanks.
