Since the issue is intermittent and from the log and code review, It is found that the shared variable `fileCache` is used in comparison with the `newFileCache` where the comparison invokes the iterator method in AbstractList class. Since based on vector documentation it was evident that listIterator are fail-fast iterators and hence it would be better to make a separate local copy of vectors for comparing operations.

Looks like there's a title mismatch blocking you from integrating but changes LGTM.
