Subject [jira] [Commented] (OPENJPA-2007) Setting query hint "openjpa.FetchPlan.Isolation" results in misleading warning
Date Wed, 25 May 2011 21:37:47 GMT


Jeremy Bauer commented on OPENJPA-2007:

Still working on a jUnit for this issue.  It is quirky since the behavior change is primarily
the absence of a warning in the log.

> Setting query hint "openjpa.FetchPlan.Isolation" on a query results in this misleading
warning being printed in the log:
> WARN   [main] openjpa.Runtime - "openjpa.FetchPlan.Isolation" is not a supported query
hint. May be you meant "openjpa.FetchPlan.LRSSize"?
> The supported hint map in JDBCPersistenceProductDerivation adds key openjpa.FetchPlan.TransactionIsolation,
which is incorrect.  It should be adding openjpa.FetchPlan.Isolation instead.
> Note: Even though a warning is issued, provided the database supports query-level isolation
level switching, the hint handler does apply the isolation level to the query.
