> ----------------------------------------------------------------------
>
> 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.
