    // not mean the same thing. In the first case, the null value means that
    // the resource is no longer in the repository and in the second the
    // null value means there is no change between the two versions.
    // Using these values I am not able to distinguish both case.
    // It is in contradiction with test #shouldReturnNullResourceVariant2()
    // and test #shoulReturnSameResourceVariant(). However I haven't found
    // another way to handle this case. Maybe something can be
    // done with ThreeWayDiffEntry.scan(tw) to force including in the cache
    // some entry even if they have not changed. For example,
    // ThreeWayDiffEntry.scan(tw,includedSource) or maybe try preventing the variant
    // tree to return null by walking throught the repository and looking for the file...
