Hello,
We have an application that uses Deltaspike 1.6.1 on TomEE 1.7.1 with
EclipseLink 2.6.2. Java version is 1.8.0_74.
During a batch operation (BatchEE 0.3-incubating) using 32 threads we sometimes
get the following exception:
java.lang.NullPointerException

se.company.OurRepository$$DSPartialBeanProxy.save(Unknown Source)...
Our repository class is defined like this:
@Repository
@ApplicationScoped
public interface OurRepository extends EntityRepository<OurEntity, Long> {
...
}
And is called from a @Stateless bean.
The entity itself is not null, since when we tried that in a unit test we got a
different exception.
The stacktrace suggests that the bean manager instance is null, but we have no
idea how that can be. Are we missing something here? Do you have any idea how
this exception can arise?
Best regards,
Mattias Kettil
