> Project: Lucene - Core

> Components: core/index
> Affects Versions: 4.6.1
> Reporter: Vitaly Funstein
> Priority: Critical
> Attachments: CommitReuseTest.java

> {{StandardDirectoryReader}} assumes that the segments from commit point have deletes, when they may not, yet the original SegmentReader for the segment that we are trying to reuse does. This is evident when running attached JUnit test case with asserts enabled (default):
> {noformat}
> java.lang.AssertionError
