Vemund Østgaard commented on DERBY-3445:
----------------------------------------
I haven't found any problems with this change and ant 1.6. My experience with
ant 1.6 is that to get things to work you need to use one of the workarounds
described here: http://ant.apache.org/faq.html#delegating-classloader-1.6:
1. put all external libraries you need in CLASSPATH as well this is not
what you want, otherwise you wouldn't have found this FAQ entry.
2. put all external libraries you need in ANT_HOME/lib or .ant/lib. This
probably still isn't what you want, but you might reconsider the .ant/lib
option.
3. Always start Ant with the -lib command line switch and point to your
external libraries (or the directories holding them).
4. remove the class that loads the external library from the coreloader.
So, basically my change has no effect with ant 1.6, it neither helps nor harms
as far as I can understand. I am able to test with ant 1.6 if I for instance
use the -lib option with ant.
If you are using ant 1.7 with my patch you just need to have junit.jar under
your tools/java/ directory where the ant properties expect it to be. In my work
environment that is a better solution than the various workarounds for ant 1.6.

> It is a bit tricky to use EMMA to measure code coverage for the derby testing.
> Modifications must be made to the source both to avoid problems with the
> SecurityManager and individual tests. It would be good if these modifcations
> could be done once and for all so that it was easier for anyone to run the
> tests with EMMA.
> It would also be good to have ant tasks that would make it even easier to run
> the tests with EMMA.
