crocket created LUCENE-4882:
-------------------------------
Summary: FacetsAccumulator.java:185 throws NullPointerException if
it's given an empty CategoryPath.
Key: LUCENE-4882
URL: https://issues.apache.org/jira/browse/LUCENE-4882
Project: Lucene - Core
Issue Type: Bug
Components: modules/facet
Affects Versions: 4.2
Reporter: crocket
Priority: Critical
When I want to count root categories, I used to pass "new CategoryPath(new
String[0])" to a CountFacetRequest.
Since upgrading lucene from 4.1 to 4.2, that threw
ArrayIndexOfOutBoundsException, so I passed CategoryPath.EMPTY to a
CountFacetRequest instead, and this time I got NullPointerException.
It all originates from FacetsAccumulator.java:185
Does someone conspire to prevent others from counting root categories?
