Subject [jira] Issue Comment Edited: (DERBY-4127) ArrayIndexOutOfBoundsException in DatabaseMetaDataTest when run in Soft Upgrade mode
Date Sat, 04 Apr 2009 18:34:14 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4127?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12695643#action_12695643

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

Of one the test cases inside DboPowersTest actually leads to a hard upgrade of wombat to 10.5.
This seems to
precipitate the error. (DboPowersTest works on the assumption that the hard upgrade here is
just a normal reboot;
the intention being to just test the powers to specify hard upgrade. Obviously, when we have
created wombat with 10.4 that assumption no longer holds. But why a hard upgrade should make
the subsequent DatabaseMetaDataTest fail is another matter..)

>             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

> 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)
