It maybe due to your environment, including your filesystem, since locking
rely on the filesystem. I've tested with sun jvm 1.5 and 1.6, on windows
Vista, windows XP and linux.

It may also simply be due to a slowness of your box, try to increase the
join time at the end of the test (use 60000 instead of 10000) for instance),
and see if it works. To get more details on what is happenning  you can set
debugging to true on the lock strategy in the test:
    private CacheManager newCacheManager(IvySettings settings) {
        CacheManager cacheManager = new CacheManager(settings, new
File("build/test/cache"));
        cacheManager.setLockStrategy(new ArtifactLockStrategy(*true*));
        return cacheManager;
    }
