getCache() should throw IllegalStateException if the EMF has been closed.
--------------------------------------------------------------------------
Key: OPENJPA-1581
URL: https://issues.apache.org/jira/browse/OPENJPA-1581
Project: OpenJPA
Issue Type: Bug
Reporter: Michael Dick
Assignee: Michael Dick
Priority: Minor
Fix For: 2.0.0
Per javadoc for EntityManagerFactory.getCache():
/**
* Access the cache that is associated with the entity manager
* factory (the "second level cache").
* @return instance of the Cache interface
* @throws IllegalStateException if the entity manager factory
* has been closed
*/
public Cache getCache();
Throwing a new IllegalStateException is trivial, but throwing the same
exception we do for other operations on a closed factory is a bit more
involved.
Short reason :
* BrokerFactory.assertOpen() is not public, and the saved exception (used when
trace is enabled) is also not available outside of AbstractBrokerFactory.
* EMFImpl.getCache() caches the cache. The same object implements the JPA cache
interface and the OpenJPA StoreCache interface. Historically getting the
StoreCache does not require the EMF to be open (this may be an oversight).
