> The configuration is as follows:
> 1. We have two entities which are in parent-child relationship (class Parent, class Child
extends Parent)
> 2. The child entity is marked by the @Cacheable(false) annotation
> 3. The parent entity is not marked by the @Cacheable annotation
> 4. Shared cache configuration is set to DISABLE_SELECTIVE
> 5. Transaction type is RESOURCE_LOCAL
> The test case is:
> 1. Create an instance of the Child entity and set some properties
> 2. Persist the entity by calling the EntityManager.persist() method
> 3. Request the entity using EntityManager.find() method and make sure the returned instance
is the same which been persisted.
> 4. Clear L1 cache usign EntityManager.clear() mwthod
> 5. Repeat step 3. Here we get NPE in the BrokerImpl.find()
