Date Mon, 11 Aug 2008 19:02:46 GMT

     [ https://issues.apache.org/jira/browse/DERBY-3741?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Suran Jayathilaka updated DERBY-3741:
-------------------------------------

    Attachment: derby.log

Attaching derby.log file from the failed tests. This file is from the 
derby-10.4\tests\fail\DerbyNetClient\AuthenticationTest\testChangePasswordAndDatabasePropertiesOnly

folder.
Before running the test, I had cleaned the tests folder.

I used the following commands to run the tests.

set CLASSPATH=..\classes;..\tools\java\junit.jar;..\tools\java\jakarta-oro-2.0.8.jar
java -XX:MaxPermSize=128M -Xmx1024M -Xms512M -Dderby.tests.trace=true junit.textui.TestRunner
org.apache.derbyTesting.functionTests.tests.jdbcapi.AuthenticationTest
