According to EJB3 specification, @Timeout callback method can have REQUIRED, REQUIRES_NEW or NOT_SUPPORTED transaction attribute. I wonder if there is any case in which Timeout method will be executed with active JTA transaction?
According to my understanding about @Timeout callback method, only two REQUIRED & NOT_SUPPORTED transaction attributes are required. It would be great if someone can explain why these 3 attributes are allowed.
