> Uncovered this due to the fix for LOG4J2-2658, these failures were encountered but not logged previously.
> AbstractPathAction.execute uses Files.walkFileTree, which can fail if any file in the tree is deleted, regardless of whether or not it's related to files we're deleting. The walkFileTree API doesn't provide any way to continue in this case.
