> ExtendedNumericComparator does not compare correctly NULL and UNDEFINED

> Key: GEODE-9018
> URL: https://issues.apache.org/jira/browse/GEODE-9018
> Project: Geode
> Issue Type: Bug
> Components: querying
> Reporter: Alberto Gomez
> Assignee: Alberto Gomez
> Priority: Major
> Labels: pull-request-available
> Fix For: 1.15.0
>
>
> The compareTo method of ExtendedNumericComparator does not compare correctly
> UNDEFINED and NULL.
> UNDEFINED should always be smaller than anything but it is not always so when
> compared with NULL.
> compareTo(NULL, UNDEFINED) returns 1, which is correct
> but
> compareTo(UNDEFINED, NULL) returns 1, and it should return -1.
> This could provoke that queries with indexes do not return the right results
> when these values are involved.
