Uwe Schindler updated LUCENE-1859:
----------------------------------
Priority: Minor (was: Major)
> TermAttributeImpl's buffer will never "shrink" if it grows too big
> ------------------------------------------------------------------
>
> Key: LUCENE-1859
> URL: https://issues.apache.org/jira/browse/LUCENE-1859
> Project: Lucene - Java
> Issue Type: Bug
> Components: Analysis
> Affects Versions: 2.9
> Reporter: Tim Smith
> Priority: Minor
>
> This was also an issue with Token previously as well
> If a TermAttributeImpl is populated with a very long buffer, it will never be able to
reclaim this memory
> Obviously, it can be argued that Tokenizer's should never emit "large" tokens, however
it seems that the TermAttributeImpl should have a reasonable static "MAX_BUFFER_SIZE" such
that if the term buffer grows bigger than this, it will shrink back down to this size once
the next token smaller than MAX_BUFFER_SIZE is set
> I don't think i have actually encountered issues with this yet, however it seems like
if you have multiple indexing threads, you could end up with a char[Integer.MAX_VALUE] per
thread (in the very worst case scenario)
> perhaps growTermBuffer should have the logic to shrink if the buffer is currently larger
than MAX_BUFFER_SIZE and it needs less than MAX_BUFFER_SIZE
