Spring autowired bean for @Aspect aspect is null

I am running the integration test where aspect j is used. I don't have any prior knowledge related to aspect j but when I ran the same test on eclipse it is running fine. One thing I noticed is that beans were getting autowired correctly(by spring aop plugin or aspectj, i am not sure) but after that, they are getting set to null. All of the below objects (like DynamicResolverLocator)are getting set as null.
