fabio martelli created OPENJPA-2302:
---------------------------------------
Summary: Slice support for QueryCompilationCache
Key: OPENJPA-2302
URL: https://issues.apache.org/jira/browse/OPENJPA-2302
Project: OpenJPA
Issue Type: Improvement
Components: slice
Affects Versions: 2.2.1, 2.3.0
Reporter: fabio martelli
Fix For: 2.3.0
It seems that slice doesn't support QueryCompilationCache.
By running the following test case ...
public class TestQueryCompilationCache extends SliceTestCase {
/**
* Specify persistence unit name as System property
* <code>-Dunit</code> or use the default value as
* <code>"slice"</code>.
*/
protected String getPersistenceUnitName() {
return System.getProperty("unit", "slice");
}
@Override
public void setUp() {
super.setUp(PObject.class,
"openjpa.QueryCompilationCache", "true");
}
public void testQueryCompilationCache()
throws Exception {
OpenJPAEntityManager em = emf.createEntityManager();
em.getTransaction().begin();
em.createQuery("SELECT o from PObject o").getResultList();
em.getTransaction().commit();
em.close();
em = emf.createEntityManager();
em.createQuery("SELECT o from PObject o").getResultList();
em.close();
emf.close();
}
}
The following exception will be raised.
