> NPE when calling isCurrent() on a ParallellReader
> -------------------------------------------------
>
> Key: LUCENE-832
> URL: https://issues.apache.org/jira/browse/LUCENE-832
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index
> Affects Versions: 2.0.0, 2.0.1, 2.1, 2.2
> Reporter: Paul Dlug
> Assignee: Michael Busch
>
> As demonstrated by the test case below, if you call isCurrent() on a
> ParallelReader it causes an NPE. Fix appears to be to add an isCurrent() to
> ParallelReader which calls it on the underlying indexes but I'm not sure what
> other problems may be lurking here. Do methods such as getVersion(),
> lastModified(), isOptimized() also have to be rewritten or is this a use case
> where ParallelReader will never mimic IndexReader perfectly? At the very
> least this behavior should be documented so others know what to expect.
