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.
