> TermDocs.skipTo fails with an ArrayOutOfBoundsException from BitVector
> ----------------------------------------------------------------------

> Key: LUCENE-1054
> URL: https://issues.apache.org/jira/browse/LUCENE-1054
> Project: Lucene - Java
> Issue Type: Bug
> Components: Index, Query/Scoring, Search, Term Vectors
> Affects Versions: 2.2
> Environment: Java 1.5 and 1.6 exhibit error. OS Windows XP and Ubunbtu
> Reporter: michael streeton
> Attachments: Test4.java, TestSkipTo.java
>
>
> After a number of calls to TermDocs.skipTo, the following exception is thrown
> java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 101306
> at org.apache.lucene.util.BitVector.get(BitVector.java:72)
> at
> org.apache.lucene.index.SegmentTermDocs.next(SegmentTermDocs.java:118)
> at
> org.apache.lucene.index.SegmentTermDocs.skipTo(SegmentTermDocs.java:176)
> at org.apache.lucene.index.MultiTermDocs.skipTo(MultiReader.java:413)
> This error only occurs in 2.2 works okay in 2.1 and in 2.2 if the index is
> built using 2.1. The following demonstrates the error. The document being
> skipTo is not greater than the number of documents in the index.
