--------------------------------------
Summary: ArrayIndexOutOfBoundsException in IntRange.toString and
its siblings
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
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 in getMin() and getMax()).
The same bug is found in the DoubleRange, FloatRange, and LongRange classes.
