I have an EJB class annotated @Singleton and @Startup.
This class in turn contains an @Inject-ed EJB that is @Stateless, and this
stateless EJB has a @Persistence EntityManager.
I'm finding that, when my startup code runs and calls into the stateless,
its EntityManager is still null (see attached log). This happens under
TomEE 1.7.0 too so I don't think it's a regression. But the exact same code
was working for me once upon a time on the same system (with the same java
JDK as well) so I'm not sure what's going on. If I don't use @Startup at
all, there's never any issue reaching the injected EntityManager. Is there
any reason that CDI would not have been ready by the time a stateless
singleton would be able to run?
I'm using hibernate as a provider rather than openJPA, and it works fine
until I use this arrangement.
Using windows 10, Java 8, JDK oracle 201.
Thanks,
-Kean
