Subject [jira] Commented: (OPENJPA-1381) IllegalStateException on query method call after named query is created twice.
Date Wed, 11 Nov 2009 20:06:39 GMT

    [ https://issues.apache.org/jira/browse/OPENJPA-1381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12776626#action_12776626
] 

Albert Lee commented on OPENJPA-1381:
-------------------------------------

The limitation/requirement of using the query cache is documented in the manual.

The query cache is enabled by default, which is a problem for a JPA compliance application
that has the reported usage pattern.

Pinaki agrees using this JIRA to either:
- make the Query cache disabled by default.
- invalidate the cache at the appropriate call path
- potentially using QueryImpl.ignorePreparedQuery() to automatically by-pass the problem.

> When a query method is called (e.g. setLockMode) on a named query that has been created
twice, an IllegalStateException is thrown:
>   Query q1 = em.createNamedQuery("xxxx");
>   ,,,,
>   Query q2 = em.createNamedQuery("xxxx");
>   q2.setLockMode(READ);
> 11078  test  TRACE  [Thread-4] Tests - Caught exception and continue: java.lang.IllegalStateException:
Query is neither a JPQL SELECT nor a Criteria API query.
