There is more subtlety to this bug:
EJB 3.1 FR 13.3.7 Specification of the Transaction Attributes for a Bean’s Methods
...
- a singleton session bean’s PostConstruct/PreDestroy lifecycle callback interceptor
methods
...
- For a singleton session bean’s PostConstruct/PreDestroy lifecycle callback interceptor meth-
ods, only the REQUIRED, REQUIRES_NEW, and NOT_SUPPORTED transaction attributes may be
used.

So a lifecycle callback running through 'mandatory' is something that should never happen.

See also EJB 3.1 FR 4.8.3. Specifying 'MANDATORY' on a lifecycle callback for a singleton is actually illegal.

The real bug is that tx attributes are not properly resolved, similar to EJBTHREE-2120.
