             Summary: BytesRef.copyBytes and copyChars don't oversize
                 Key: LUCENE-5836
                 URL: https://issues.apache.org/jira/browse/LUCENE-5836
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Adrien Grand
            Assignee: Adrien Grand


When copying data from another BytesRef/CharSequence, these methods don't oversize. This is not an issue if this method is used only once per BytesRef instance but I just reviewed the usage of these methods and they are very frequently used in loops to do things like:
 - keep track of the top values in comparators
 - keep track of the previous terms in various loops over a terms enum (lucene49 DV consumer, BlockTreeTermsWriter)
 - etc.

Although unlikely, it might be possible to hit a worst-case and to resize the underlying byte[] on every call to copyBytes? Should we oversize the underlying array in these methods?
