@Singleton @Startup classes inheriting from a class containing a @PostConstruct method will not create a transaction

During an update from wildfly 8.2.0.Final to 11.0.0.Final I have noticed the following issue:

Given an abstract base class B with an @PostConstruct annotated method and a derived class D with the annotations @Singleton and @Startup. When the @PostConstruct method is called, no transaction is started.

According to the EJB 3.2 Specification section 4.8.3, I would expect the container to start a new transaction, as the default transaction attribute is REQUIRED.

I have attached source for a war showcasing this issue. On deploying the resulting war on a new wildfly instance, the log should contain the following two lines:

{{14:13:06,410 INFO [stdout] (ServerService Thread Pool – 20) Singleton Hierarchy: transaction status: 6
14:13:06,410 INFO [stdout] (ServerService Thread Pool – 58) Singleton2 Standalone: transaction status: 0}}

A transaction status of 6 says that no transaction exists, while a transaction status of 0 implies that a transaction is ongoing. The war shows that this issue occurs only when using a class hierarchy. I expect the status 0 for both cases.

Through testing I noticed that this issue exists since wildfly 9.0.0.Final. I could not find a reason for this behavior from the list of issues for the 9-series release, however.
