> The `openAndWarmup()` method is invoked twice from `purge()` method of `org.apache.maven.index.context.DefaultIndexingContext` which results into `OverlappingFileLockException` during the index re-indexing, because the `openAndWarmup()` method call creates a `FileLock` for an index and the second call tries to create and add the second `FileLock` for the same index which is erroneous:
