Major When a repository is deleted in Nexus the search index context is not always deleted properly.
If you later try to recreate the repository the old search index context will be found, and this will result in an error. The only way to recover from this is to shut the server down. manually remove the old index context from disk. Then restart and rebuild the index for the affected repository.
Expected: If an old (stale) indexing context is present on disk when a repository is being created we should delete it, and create a new one.
