TestPointFields.testIntPointFieldMultiValuedRangeFacet fails for seed

This reproduces:
gradlew :solr:core:test --tests "org.apache.solr.schema.TestPointFields.testIntPointFieldMultiValuedRangeFacet" -Ptests.jvms=6 -Ptests.jvmargs=-XX:TieredStopAtLevel=1 -Ptests.seed=8E7691162850731 -Ptests.file.encoding=ISO-8859-1
Line 391.

From my build emails, this test has failed twice last year.  I checked if it's related to Mike Drob's last commit RE a static analysis discovered refactoring, and it isn't.

The facet range is:
facet.range.start=-1899777513&facet.range.end=2145600248
That is really quite a wide range. Both the start and end value are integers, but subtracting the two overflows an integer.  This suggests an integer overflow error somewhere.
