StandardQueryCache not alive after EntityManagerFactory is re-created
---------------------------------------------------------------------
Key: HHH-5346
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-5346
Project: Hibernate Core
Issue Type: Bug
Components: caching (L2)
Affects Versions: 3.5.3
Environment: Ubuntu 8.04
Java SDK 1.6_07
Tomcat 6.0.20
Hibernate-core: 3.3.2.GA
Hibernate-annotations3.4.0.GA
Hibernate-entitymanager: 3.4.0.GA
EhCache 2.1.1
Specific databse product: Data Federator (SAP)
JAX-WS stack: 2.1.7 RT
Reporter: Franck Michel
Hi all,
I'm facing a trouble that no post seems to be treating yet: I use Hibernate through
the JPA API + EhCache as a 2nd level cache.
In the appli.
After a long inactivity period, I happen to get a PersistenceException at the first
request to my entity manager. In this case, I create a new EntityManagerFactory, and a new
EntityManager. At that moment:
- the first request raises an exception about the StandardCacheQuery not being alive.
- most curious, the second request works fine.
The exception stack is listed at the end. Other information about the context follows.
Thx in advance for your help. Regards.
Franck.
- ehcache.xml config:

same exception happens with or without the StandardQueryCache region configuration.
