TimedCachePolicy.insert... Attempt to insert duplicate entry
Hello everyone,
I see this stack trace very intermittently when my bean attempts to run a JPA query, and I'm looking for ideas on what the problem could be and how to solve it.
I'm running with JBoss 5.0.1GA on linux with an Oracle data source. The oracle-ds.xml has the directive "<security-domain>EncryptOraclePassword</security-domain>".
java.lang.IllegalStateException: Attempt to insert duplicate entry

The named query:
