LUCENE-7946: Fix CharTermAttribute.setLength's bounds check
> CharTermAttributeImpl.setLength missing bounds check
> ----------------------------------------------------
>
> Key: LUCENE-7946
> URL: https://issues.apache.org/jira/browse/LUCENE-7946
> Project: Lucene - Core
> Issue Type: Bug
> Components: modules/analysis
> Reporter: Robert Muir
> Attachments: LUCENE-7946.patch
>
>
> CharTermAttribute.setLength partially checks for out of bounds values
> (exceeds term buffer array size) but doesn't check for negative values.
> This can be confusing as then the negative length will only fail or misbehave
> much later, for example with the first iteration of LUCENE-7940. It fails
> later only when we call toString() afterwards.
