Provide a framework to test upgrade between point releases. Currently, the 
upgrade testing happens between two major versions.

                 Key: DERBY-5164
                 URL: https://issues.apache.org/jira/browse/DERBY-5164
             Project: Derby
          Issue Type: Improvement
          Components: Test
    Affects Versions: 10.7.1.1, 10.6.2.1, 10.5.3.0, 10.4.2.0, 10.3.3.0, 
10.2.2.0, 10.1.3.1, 10.0.2.1
            Reporter: Mamta A. Satoor


DERBY-5121 found a corruption problem caused by triggers in DERBY release 
10.7.1.1 A fix for this has been provided in trunk(10.8) and the 10.7 codeline. 
10.7.1.1 database upgrade to any one of these 2 codelines will fix the triggers 
causing the corruption. I was able to write upgrade tests for 10.8 codeline but 
not for 10.7 codeline. The reason for this can be found in the comment insdie 
org.apache.derbyTesting.functionTests.tests.upgradeTests.UpgradeRun:baseSuite 
    * Changes are only added if the old version is older than
    * then version the changes represent. Thus Changes10_2
    * is not added if the old database (upgrade from) is already
    * at 10.2, since Changes10_2 is intended to test upgrade
    * from an older version to 10.2.

The last line in the comment "since Changes10_2 is intended to test upgrade 
from an older version to 10.2." is not really true specifically for DERBY-5121. 
We want to test upgrade from 10.7.1.1 to next point release/codeline of 10.7.

Providing this framework should not be too hard. I just wanted to create this 
jira so we can keep track of the issue.
