Without this change the updated test fails as:

FAILED     GetCanonicalPath::goodPathsUnix '[3] /../../../../../a/../../b/c, /b/c'
org.opentest4j.AssertionFailedError: expected: </b/c> but was: </../b/c>

FAILED     GetCanonicalPath::goodPathsUnix '[5] /../../../../../a/../../../../b/c, /b/c'
org.opentest4j.AssertionFailedError: expected: </b/c> but was: </../b/c>
