I just noticed that win-tests.py has a --javahl option. This is cool, but it does not work. The reason is that it refers to a junit Python object that is not defined. In my case, I just removed it since I have junit.jar in the lib/ext folder for my JRE. I am guessing someone planned to add a --junit option of some kind? Not sure the right change, so I am not attempting a patch.
This was with 1.8.0-rc1 but I assume trunk has same problem. It is nice to be able to run the tests this way since it sets up everything needed. Removing the Junit reference caused the tests to run for me. -- Thanks Mark Phippard http://markphip.blogspot.com/
