> Some code uses BytesRef as if it were a "String", in this case consumers of TermToBytesRefAttribute.
> The thing is, while our general implementation works on char[] and then populates the consumers BytesRef,
> not all TermToBytesRefAttribute implementations do this, specifically ICU collation, it reuses the bytes and simply sets the pointers:
> {noformat}
>   @Override
>   public int toBytesRef(BytesRef target) {
>     collator.getRawCollationKey(toString(), key);
>     target.bytes = key.bytes;
>     target.offset = 0;
>     target.length = key.size;
>     return target.hashCode();
>   }
> {noformat}
> Most of the blame falls on me as I added this to the queryparser in LUCENE-2514.
> Attached is a patch so that these consumers re-use a 'spare' and copy the bytes when they are going to make a long lasting object such as a Term.
