PostConstruct and PreDestroy methods of Singletons with container-managed transactions are transactional.
What are the semantics of the above statement?
Why in the first place do these methods have to be in a transaction context in the first place?

Hi Anirudh,
As you might know that Transactional Attributes comes into picture, when your service is associated with a Transaction. If you do not want any transaction from your service then you can use NOT_SUPPORTED Transactional Attribute. But sometimes it can be useful to complete transactional activities during the PostConstruct and PreDestroy life cycle interceptor callbacks for example : logging purpose. So by making PostConstruct and PreDestroy transactional, gives freedom to the developer to write any transactional statements in that.
