I’m having an issue with an index when adding category paths to a document. They seem to be added without issue for a long period of time, then for some unknown reason the addition fails with an ArrayIndexOutOfBounds exception. Subsequent attempts to add category paths fail with the same exception. I’ve run CheckIndex on both the index and the taxonomy directory and both come back as clean with no issues. I cannot fix the index because according to lucene it is not broken. Could this be a bug in lucene? Below is the stack trace when the exception occurs:
