-------------------------------------------------------------

I see the following errors on the test run on Java 7 on Sol32. See http://dbtg.foundry.sun.com/derby/test/Daily/jvm1.7/testing/Limited/testSummary-1378997.html

1) test_01_basicSyntax(org.apache.derbyTesting.functionTests.tests.lang.UserDefinedAggregatesTest)java.sql.SQLException:
DERBY AGGREGATE 'MODE' already exists.
2) test_01_basicSyntax(org.apache.derbyTesting.functionTests.tests.lang.UserDefinedAggregatesTest)java.sql.SQLTransactionRollbackException:
DERBY AGGREGATE 'MODE' already exists.

Probably caused by running the test cases in a different order on that platform.

> Nicolas Dufour in an email thread titled "functions and list" started on November 2,
2005 requests the ability to create user defined aggregates.
> This functionality used to be in Cloudscape. It was disabled presumably because it was
considered non-standard. However, most of the machinery needed for this feature is still in
the code. We should re-enable user defined aggregates after we agree on acceptable syntax.
