Uwe Schindler updated LUCENE-2154:
----------------------------------
Attachment: LUCENE-2154.patch
I had some more fun. Made ProxyAttributeSource non-final and added class name
policy to also contain the corresponding interface (to make stack traces on
errors nicer).
Here the example output:

> Key: LUCENE-2154
> URL: https://issues.apache.org/jira/browse/LUCENE-2154
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: Flex Branch
> Reporter: Michael McCandless
> Fix For: Flex Branch
>
> Attachments: LUCENE-2154.patch, LUCENE-2154.patch
>
>
> The flex API allows extensibility at the Fields/Terms/Docs/PositionsEnum
> levels, for a codec to set custom attrs.
> But, it's currently broken for Dir/MultiReader, which must somehow share
> attrs across all the sub-readers. Somehow we must make a single attr source,
> and tell each sub-reader's enum to use that instead of creating its own.
> Hopefully Uwe can work some magic here :)
