SpringBoot @Transactional not working when using two contexts and @Configurable weaved with AspectJ

Spring Boot 1.5.9.RELEASE

Provided test case where inside a @Transactional method, the previously persisted entity is not present in entity manager, eg:

    @Transactional
    public void doWork() {
        TestTable entity = testTableRepository.save( new TestTable( "test" ) );
        Assert.assertTrue( entityManager.contains( entity ) );
    }

From my investigation, issue is related to transaction managers mixing from the two contexts because of AnnotationTransactionAspectcaching of a transaction manager from previous context. Thus, the @Transactional method uses the previous context transaction manager (weaved aspect), and the repository save method will use the current context transaction manager creating a new temporary transaction that closes immediately after entity is persisted.
