Executing a cached query doesn't properly cache results after DataCache eviction
--------------------------------------------------------------------------------
Key: OPENJPA-1511
URL: https://issues.apache.org/jira/browse/OPENJPA-1511
Project: OpenJPA
Issue Type: Bug
Affects Versions: 2.0.0-beta
Reporter: Rick Curtis
Attachments: TestCache.java
When doing some testing I found that the QueryCache sometimes doesn't put
results into the DataCache.
I haven't had time to debug the problem, but I'm opening this JIRA so I can
attach the test case I've created.
The test scenario is as follows:
String query = "Select t FROM Item t where 1=1 ORDER BY t.id";
items = em.createQuery(query,Item.class).getResultList();
assertTrue(storeCache.contains(Item.class, items.get(0).getId()));
// Make sure that all of the results are in the DataCache.
for(Item o : items){
assertTrue(storeCache.contains(Item.class, o.getId()));
}
storeCache.evict(Item.class,items.get(0).getId());
// Evict one result
assertFalse(storeCache.contains(Item.class,items.get(0).getId()));
// Executing the same query should re-populate the datacache
items = em.createQuery(query,Item.class).getResultList();
assertTrue(storeCache.contains(Item.class, items.get(0).getId())); // fails here
