@Transactional should fail in @PostConstruct if AspectJ transaction aspect not initialized yet

[cdalexndr]

Using Aspectj mode with runtime aspectj weaver.

Inside a @PostConstruct, calling a method with @Transactional doesn't start a transaction.
The transactional aspect forwards call to the method, but no transaction is started. This is an invalid behavior, I was expecting an exception.

Spring Boot 2.4.4

In some cases, using spring.main.lazy-initialization=true can delay @PostConstruct until transactional system works.
