> IndexPublisher does not protect "read consistency" over published context.
> This affects only contexts that are the new MergedIndexingContext. These --
> newly introduced context types in 4.1.0 -- are simply "logical merged view"
> of other IndexingContexts. When some change -- and async commit -- happens in
> some of the member contexts, a Lucene exception is thrown preventing proper
> publishing of the context.
> Typical top lines of these stack traces:
