If this happens only at deploy time, it looks like the ejb container is instantiating the cdi proxy before some CDI scoped resources are in place, but at that time no real mapper method is called. So if the stateless bean is then returned to the pool just to wait for a client, the proxy will be serialized and then deserialized when a real client uses the stateless bean, but at that time all the CDI beans are ready so it works. Its just a theory, apparently this case is not present in weld, maybe only in webbeans?

Recently we change some of the design of our application.
Since we made that change this issue has resurfaced and now it is interfering with the proper functionality of our application.
We have a MessageDrivenBean (the Receiver) in our application, which receives a JMS Message and delegates processing that message to another Stateless Session Bean(the MessageRouter).
After going through some of our classes it will invoke a method on a another Stateless Session Bean (the MyBatisPaymentRequestRepository), which needs the Mapper.
The injection of the Mapper into the constructed MyBatisPaymentRequestRepository fails due to this NullPointerException in getting the Mapper from the SerializableMapperProxy.
After some time the initialization of the SerializableMapperProxy or the SqlSessionFactory is complete and then the application is going to work properly, but processing the first couple of JMS-message has already failed.

Hi @mcbeelen, I have done some important changes in beta5. please take a look at: http://www.mybatis.org/cdi/changes.html
So please upgrade to beta5 and tell me if the problem is still there.

Hi @mnesarco ,
We upgraded to beta5 and tweaked our logging.
The behaviour as we currently see it, is this:
- mybatis.cdi.Extension finds 5 Mappers in
processAnnotatedType(). - mybatis.cdi.Extension does not create a bean for all found mappers in
afterBeanDiscovery() - As soon a OpenEJB.startup finds a object, which needs on of the 'uninitialized mappers' to throws an UnsatisfiedResolutionException.

Further debugging gave us the insight that processInjectionTarget() is not being called for the Field Injection Point, which later causes the UnsatisfiedResolutionException.

@mnesarco : Could the process to make a 1.0.0-beta6 release be started?
We would like to use the solution for this issue in our project, but prefer to use released versions instead of SNAPSHOTs.

Hi @mcbeelen : I think it would be great to wait some news from issues #19
and #5. If they test the beta6 and confirm it solves the issues we can then
release it and help more users.
But if it is critical to you, you can ask to @hazendaz, maybe if he has
time he can push the release sooner.

I did a quick overall review, cleaned up a few very trivial issues, upgraded mockito to 2.7.0 and fixed mockito deprecations. I'll push the release for beta6. It's rather simple to do and takes about 10 minutes max. The binary should show up though in central in about 2 to 3 hours from now.
