> This bug was found when doing soft upgrade testing from Derby version 10.4.2.0 to 10.5.1.0 (RC1)
> Steps followed are as follows.
> 1. Run setEmbeddedCP.bat from version 10.4.2.0's bin folder
> 2. In a test folder run ij
> 3. create system/wombat database.
>     ij> connect 'jdbc:derby:system/wombat;create=true';
> 4. exit ij
> 5. Copy the 10.5.1.0 derby jars (from lib folder) and the derbyTesting.jar from 10.4.2.0 to the test folder and set classpath with them (including junit and ORO)
> 6. Run suites.All
>      java -Xmx512M -Xms512M -Dderby.tests.trace=true junit.textui.TestRunner org.apache.derbyTesting.functionTests.suites.All
> Result:
> Tests run: 10479, Failures: 56, Errors: 34

> I did not see anything in the derby.log from the tests that seemed to be related to this.
> Note that this test passed when run by itself, and also when run after a couple of failing tests (namely org.apache.derbyTesting.functionTests.tests.jdbcapi.BlobClob4BlobTest and org.apache.derbyTesting.functionTests.tests.jdbcapi.UpdatableResultSetTest)
