Failure in BlobClob4BlobTest due to wrong results being returned
----------------------------------------------------------------

                 Key: DERBY-4135
                 URL: https://issues.apache.org/jira/browse/DERBY-4135
             Project: Derby
          Issue Type: Bug
          Components: Regression Test Failure
    Affects Versions: 10.5.1.0
         Environment: Windows Vista 64, Sun JDK 1.6.0_10, Junit 3.8.2 
            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)

The assertion failure is caused by wrong results being returned.

Steps to reproduce 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 testcase
     java -Xmx512M -Xms512M -Dderby.tests.trace=true junit.textui.TestRunner org.apache.derbyTesting.functionTests.tests.jdbcapi.BlobClob4BlobTest

The stack trace specific to this failure is as follows.
