Description

The equals method in the range query has the collator comparison implemented as:
(this.collator != null && ! this.collator.equals(other.collator))

When this.collator = null and other.collator = someCollator this method will incorrectly assume they are equal.

So adding something like

(this.collator == null && other.collator != null) would fix the problem
