Kathey Marsden commented on DERBY-4127:
---------------------------------------
the key is that it has to be run on a soft upgraded (from 10.4) database. i.e.
Create the database system/wombat with 10.4.2.0 and then run with the 10.4
testing jar and the 10.5 product jars, so you wouldn't have seen it in your
normal test runs.
As for what mode it is run in, that is a really excellent point. This is the
10th time the test is run in the test suite that it fails. What variation of
the test that is I don't know, but it would be worth trying to figure out so we
can get a smaller repro than running the whole suite.

> 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
> The stack trace is as follows.
