Well that really, really sucks. It appears that my version of
DerbyLoader.java on disk is corrupt, and that is my *only* copy. Don't
get me started on why I don't yet have a working backup strategy.
I know what I need to do and can do it again, but that was a lot of work
down the drain. Sigh...
Basically what I had written was a "child-first" classloader that loads
from its search path *before* it loads from the parent. I don't think
you really need that, Deepa, your classloader works fine. The usage of
interfaces that you see in the rest of the code would work just as well
for a standard URLClassLoader.

Thanks Andreas for pointing out the new case added to phaseTester. I had not noticed the change as it was committed after I uploaded my first patch. I have added this test to UpgradeTester and also updated the master. The new patch is uploaded as 'derby-1075-v2.diff'. With this patch, I have built and run the new upgrade test on WinXP using Sun JDK 1.4.2. Once this patch gets reviewed and committed, it will replace phaseTester.java and runPhases.ksh and we can remove these files.
David, thanks for uploading your classloader work. I extracted the jar file using jar command but I find DerbyLoader.java in unreadable format. I am curious to understand what you have done but do not plan to work on it immediately. So whenever you get time, please check the jar file to see if you are able to read DerbyLoader.java.
Combine the script and the test available for upgrade testing into a java test

Separating a part of DERBY-514 into a sub-task. This sub-task is to combine the
script 'runphases.ksh' and the java file 'phaseTester.java' into a single java
test. This will help to later add the upgrade tests into the regression suite.
Also, this sub-task can be done independent of DERBY-1049 which is blocking
DERBY-514.
