I'm running on Ubuntu 8.04.2. When it failed, I got message similar as yours:

test_getCanonicalPath	Failure	null expected:<...ild/test/luni/folder[1/folder]2> 
but was:<...ild/test/luni/folder[]2>

junit.framework.ComparisonFailure: null 
expected:<...ild/test/luni/folder[1/folder]2> but was:<...ild/test/luni/folder[]2>
