> The PayloadProcessorProvider has a broken API, this should be fixed. The 
> current trunk mimics the old behaviour, but not 100%.
> The PayloadProcessorProvider API should return a PayloadProcessor based on 
> the AtomicReader instance that gets merged. As AtomicReader do no longer know 
> the directory they are reside (they could be e.g. FilterIndexReaders, 
> MemoryIndexes,...) a selection by Directory is no longer possible.
> The current code in Lucene trunk mimics the old behavior by doing an 
> instanceof SegmentReader check and then asking for a DirProvider. If 
> something else is merged in, Payload processing is not supported. This should 
> be changed, the old API could be kept backwards compatible by moving the 
> instanceof check in a "convenience class" DirPayloadProcessorProvider, 
> extending PayloadProcessorProvider.
