It looks like the field infos of your index went out of sync with data
stored in the files about points.
Can you run CheckIndex on your index (potentially with the `-fast` option
so that it only verifies checksums)? It could be that one of these two
parts of the index got corrupted.
Since you were able to modify the way add(IndexableField) is implemented,
I'm wondering if you are running a fork of Lucene? If yes, maybe you did
some changes that triggered this bug?
Otherwise is your application:
- using IndexWriter.addIndexes?
- customizing merging in some way, eg. by wrapping the merge readers?
