Robert Muir commented on SOLR-4723:
-----------------------------------
It might be that trunk uses Double.compare (from a java7 commit?) and branch_4x
does this:
{code}
if (v1 > v2) {
return 1;
} else if (v1 < v2) {
return -1;
} else {
return 0;
}
{code}
If so this is not right, because NumericUtils documents it is consistent with
Double.compareTo and Float.compareTo, so something needs to be fixed.
> sort order different in branch_4x than trunk
