In this case, the attribute is reported as a common attribute since the only change is the order of static and private modifiers. Hence, it is not reported inside attributeDiffList.
For the common attributes, the previous logic mapped the entire subtree in case of having the isomorphic subtrees on both sides, but due to the change in the order of modifiers, the subtrees are not isomorphic anymore.
