Subject [jira] Commented: (DERBY-4127) ArrayIndexOutOfBoundsException in DatabaseMetaDataTest when run in Soft Upgrade mode
Date Fri, 03 Apr 2009 04:05:13 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12695228#action_12695228
] 

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.

>             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

> 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.

> 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)
