Subject [jira] [Created] (OPENJPA-2007) Setting query hint "openjpa.FetchPlan.Isolation" results in misleading warning
Date Wed, 25 May 2011 19:53:47 GMT
Setting query hint "openjpa.FetchPlan.Isolation" results in misleading warning

                 Key: OPENJPA-2007
             Project: OpenJPA
          Issue Type: Bug
          Components: jdbc
    Affects Versions: 2.1.0, 2.0.1, 2.0.0, 2.2.0
            Reporter: Jeremy Bauer
            Assignee: Jeremy Bauer
            Priority: Minor

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.
