> It seems that we use
> the symptom seems to be that we cache EntityManager's in JpaContext, which
> might be ok if they are proxied thread-locals; however the underlying aren't
> disposed of.
> We notice that EclipseLink creates a "NoServerPlatform", meaning that it
> doesn't recognise us as being in a container.
> We also notice that JPA creates an LocalContainerEntityManagerFactoryBean,
> whereas perhaps it should create a LocalEntityManagerFactoryBean.

> some docs:
> [https://www.eclipse.org/eclipselink/documentation/2.6/solutions/testingjpa001.htm]
> [https://www.baeldung.com/jpa-hibernate-persistence-context] - we want to use
> "transaction-scoped" persistence context rather than "extended" ... and we
> are, I think.
