Solved...just needed some more cleanup in the WEB_INF directory.
Removed appengine-testing.jar, appengine-api-labs.jar, appengine-api-
stubs.jar.
Moved them to test folder, added again to the classpath (maybe Eclipse
did not update build path correctly before...sometimes happens) to
make tests work, and it goes.
This is stated in the test suite documentation, maybe a line in the
development server section could help.
Regards
Lorenzo
