Simon Willnauer commented on LUCENE-4919:
-----------------------------------------
I am not getting why this should return the same as Arrays.hashCode, can you
elaborate on this a bit?
> IntsRef, BytesRef and CharsRef return incorrect hashcode when filled with 0

> URL: https://issues.apache.org/jira/browse/LUCENE-4919
> Project: Lucene - Core

> Components: core/other
> Affects Versions: 4.2
> Reporter: Renaud Delbru
> Fix For: 4.3
>
> Attachments: LUCENE-4919.patch
>
>
> IntsRef, BytesRef and CharsRef implementation do not follow the java
> Arrays.hashCode implementation, and return incorrect hashcode when filled
> with 0.
> For example, an IntsRef with \{ 0 \} will return the same hashcode than an
> IntsRef with \{ 0, 0 \}.
