Kathey Marsden commented on DERBY-4127:
---------------------------------------
I tried running lang.CollationTests and upgredeTests._Suite independently with
the soft upgrade setup, and did not see the issue. Suran also tried running
DatabaseMetaDataTest on its own and it didn't reproduce. I don't immediately
see other configurations in which it is run.

> Key: DERBY-4127
> URL: https://issues.apache.org/jira/browse/DERBY-4127
> Project: Derby
> Issue Type: Bug
> Components: Regression Test Failure
> Affects Versions: 10.5.1.0
> Environment: Windows Vista 64, Junit 3.8.2, Sun JDK 1.6.0_10
> Reporter: Suran Jayathilaka
> Priority: Critical
>
> 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
