Michael Busch updated LUCENE-781:
---------------------------------
Attachment: lucene-781.patch
This patch:
* Adds the new class MultiSegmentReader which contains almost
all code from MultiReader, except the public constructor.
* Makes MultiTermEnum, MultiTermDocs and MultiTermPositions
inner, static classes of MultiSegmentReader.
* Adds the method isCurrent() to MultiReader, which recursively
checks if all subreaders are up to date.
* MultiReader now throws UnsupportedOperationException when
isOptimized() or getVersion() is called.
* Enables the isCurrent() test in TestMultiReader that was
disabled due to this issue.
All tests pass.
> NPE in MultiReader.isCurrent() and getVersion()
