> Key: LUCENE-8174
> URL: https://issues.apache.org/jira/browse/LUCENE-8174
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/index
> Affects Versions: 7.2
> Reporter: Oliver Kaleske
> Priority: Major
> Fix For: master (8.0), 7.3

> Attachments: LUCENE-8174.patch

>
> The following code produces an ArrayIndexOutOfBoundsException:
> {{ IntRange intRange = new IntRange("foo", new int[] \{ 1 }, new int[]
> \{ 2 });}}
> {{ System.out.println(intRange.toString());}}
> The exception is thrown in NumericUtils.sortableBytesToInt, which is fed an
> incorrect offset.
> The bug appears to be in IntRange.toString. I guess the for loop should read
> {{for (int d=0; d<type.pointDimensionCount()/2; ++d)}}
> instead of
> {{for (int d=1; d<type.pointDimensionCount(); ++d)}}
> because the number of dimensions is half the number of "point dimensions"
> (cf. the checks on the dimension parameter in getMin() and getMax()).
> The same bug is found in the DoubleRange, FloatRange, and LongRange classes.
