NullPointerException thrown by the BrokerImpl.find() if requesting an entity
which is marked by the @Cacheable(false) annotation
--------------------------------------------------------------------------------------------------------------------------------
Key: OPENJPA-1892
URL: https://issues.apache.org/jira/browse/OPENJPA-1892
Project: OpenJPA
Issue Type: Bug
Components: kernel
Affects Versions: 2.0.0
Environment: OpenJPA 2.0.0
PostgreSQL 8.4
Application managed env
Reporter: Nik Maximov
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()
