In Spring you can't simply call @Transactional method from the same instance, because of AOP-proxy thing. Would it be nice idea to make a self injection and call that method from self proxy instance? Do you see any drawbacks?

There are cases when it is most elegant solution available , I have used it couple of times. Spring 4.3 introduced new feature to autowire self, IMHO spring support proves it is not a bad practice. - Vipin
Maybe you can also use an exposed proxy instance via <aop:aspectj-autoproxy expose-proxy="true"/> or @EnableAspectJAutoProxy(exposeProxy = true), see SPR-10454 and JavaDoc. - kriegaex

You can see the discussion bellow this ticket. @Transactional is one of the use case for this:

Particularly interested in @Async and @Transactional use cases.
