Description

CoW prepares local dir using "reindexCount" from definition builder. BUT, while re-indexing, at the time of construction of LuceneIndexEditorContext, the builder still has non-incremented reindexCount (IndexUpdate#collectIndexEditors) thereby updating the already existing directory.

On windows, this often leads to deletion inside lucene to fail thereby failing re-index and leading to reindex loop – this can be worked around by disabling CoW temporarily.

That being said, this might be able to corrupt locally copied index.
